D'oh, stupid me. I completely forgot to check the settings and I realized all the tests were set to 'on' - my bad, sorry about that!

Just added this to 4.2.PL2

Let's see what this puppy can do!

How do I manually revert a rejected registration and allow the user to proceed?

I got this:

Spam-O-Matic Tagged username - Sneakers - Spammer Found and rejected.

How do I know the detailed reasons why it was rejected?

run this query
UPDATE `glowhostspamomatic_remotecache` SET `is_spambot`='0' WHERE (`field`='username') AND (`is_spambot`='1') AND (`data`='Sneakers')

and disable username in your settings so this wont happen again

make sure you make yourself superadmin from the config then go to AdminCP > Statistics & Logs > Glowhost Spam-O-Matic Logs
if it was his name first check on the spam o matic forums make sure he is not a spammer check his ip and email as well and only run the query if he is found to be a real person

AdminCP > Statistics & Logs > Glowhost Spam-O-Matic Logs

In the log you can see the reason why they were not allowed to register. 95% of the time it is the user name that is rejected, that is why we suggest you turn that feature off. Occasionally an IP address may be the culprit. You can double check this information if you like, but sometimes legitimate users may be using RIPE Networks, which I would say 99% are spammers. If this is the case, then you will have to manually register them. The log gives you their IP, e-mail, and username. that's enough for you to get started, then when you send them an e-mail include the link to their profile and ask them to complete the information.

How do I run a check and pull the reason for block? No reasons are given in my logs except below

Spam-O-Matic Tagged email - [email address] - Spammer Found and rejected.

That doesn't specify the reason though

I have disabled username check in the meantime, thanks for that tip.

The reason is given in your log plane as day

This mod is freaking awesome! I have always been skeptical of spam mods for some reason but I had no choice but to try it out yesterday. My site has been getting hammered by spammers in the last week.

Installed it on 4.2.0 PL 2 without any hiccups and set it to check IP and email address, and it has blocked 29 spammers in about 20 hours, while letting 17 actual accounts through with no problems.

Thank you for this mod!

Great mod!
The only one feature I miss is - menu Submit Data to StopForumSpam in adminCP options or user's profile. Sometimes "fresh" spammer registrations are passing through stopforumspam check.

This! I catch a lot of spammers who never post so I have no why of reporting there info.
