It seems that you completely missed (or ignored) post #875 in this thread, where someone else took the time to research the IP in question. Post #875's author not only provided proof of spamming by that IP going back to January 18, 2010, but they also gave you the Google link so that you could see it for yourself.

Therefore, the listing for that IP in the Stop Forum Spam database is a legitimate entry. Your concerns should be taken to Stop Forum Spam, not hashed with the author of this add-on.

Also, the add-on has the capability to allow or deny registration based on whether the registering person/bot is listed in the database:

If "check database for username" is selected:
Username found in database: allow or deny registration?

If "check database for email address" is selected:
Email address found in database: allow or deny registraton?

If "check database for IP address" is selected:
IP address found in database: allow or deny registration?

Pedigree specifically wrote these options so that you could configure this add-on to settings that matter to you. If you don't want to check IP, then don't check it. Same with username or email address. It's not Pedigree's fault that you selected options that were later found to be restricting registrations to your forum.

(And personally, if someone told me they were using their employer's "internal server" to access the Internet, I'd smell a fish. Isn't the whole point of an internal server to keep it isolated from the external Internet? How did a server that is isolated from the external Internet manage to reach your forum? :confused:

All this person had to do was register from their home IP, this would get them around the Sun IP ban, and then they could use your forum from work. Unless they're a spammer who's using the Sun IP as a relay -- in which case, the database worked as intended, wouldn't you agree?)

While I don't use this mod (I coded my own), I do use the stopforumspam website and have been extremely pleased with its results.

I'm actually able to catch 99.9% of the bots before I even check the SFS website. I'm not going to post exactly how because then a spammer might decide to fix their code. However I *do* double-check with the SFS website.

If a certain threshold of matches exist, the user gets auto-banned. If only one or two things match, then they go to the coppa/moderation group. In which case I look over the account manually and see what hit and make a determination from there...

I don't know why someone is whining about a SUN IP address... Is it not beyond possibility that a user's computer there has been compromised? When I worked for Verizon, there were people there that should have never been allowed to touch a computer. They would get them infected with all sorts of crap on a weekly basis (and the IT people would be cussing and swearing as they would walk down the halls)...

I often get hack attemps and port scanning from Amazon IPs... Is Amazon doing it? No... But people paying for their cloud computing services is...

*sigh*

Ra (aka Silkroad, aka the Sun god) got an irate email from one potential member. So what? If your time is SO bloody valuable that you can't deal with a blocked user, why are you out here arguing whether or not this mod, and the associated database, works properly? Can't you get it through your head that an IP being used to attack our board is a BAD THING? If it wasn't for the fact that this mod did work, I wouldn't have the spare time to be out here making comments.

If I was getting spammed from an IP address, I wouldn't care if it was Sun, the White House, or Bill Gates himself, that IP would get blacklisted. I've been running this mod for about two years now and have never had a single legitimate user blocked. More than 95% of the attempts to register on my board are spammers. I have a real job and don't have time to deal with that mess. This mod has made it possible for me to do both.

Is this mod perfect? No...I know of NO software that is perfect. I would dare say that most of us do not run boards for a living. The way you talk, it's important enough for you that you're concerned, and I'd guess that you're being paid to deal with it.

It doesn't work for you? You claim to be some kind of expert...what it the solution, then? You MUST have a viable solution! If you're not part of the solution, as they say, you're part of the problem.

Silkroad, you're mentioning "professional" and "Sun Microsystems" in every post... I'd hate to point it out but it may work the exact opposite on us mere mortals after a couple of times. Putting so much emphasis on it makes it sound like you're actually the janitor ;)

Anyway, standard practice for "professionals" (just as with mailserver blacklisting): contact the server owner, let them know their machine has been blacklisted and may have been compromised. *They* can -and have to if they want it to operate normally- deal directly with stopforumspam.com about their machine being blacklisted. And in your case it seems that thing really has been compromised, if it were mine I'd really appreciate someone telling me.
Complaining about either the forum that runs the mod, or the mod that queries the database, doesn't do anyone any good :)

Love, love, love, this mod. Installed a few weeks ago and it does a great job. Much thanks to the developer.

Is the http://www.stopforumspam.com/ website down for anyone else? I can't connect via web browser, ping, reverse lookup, nothing! :(

It's coming up normally for me.

Me it's giving me : [REMOTEERR] Unverfied and rejected by policy

and rejecting ALL my "normal" registrations... is their server down?

Great mod. Just installed it this morning and it's working already!

It wasnt down but GoDaddy (who, in my opinion are the internets biggest joke) decided to drop all the DNS for our domain and restarted returning NXDOMAIN for all queries (thats Non-existent Domain)

Its not the first time they decided to randomly screw with us and we are going to move the domain reg off NoDaddy to some company that isnt sh*t (in my opinion)

You might want to change the policy to log and accept on connection errors.
