Before you go blaming this mod for that, you might want to check if you have another mod that might be messing with things also. Others have had no problem doing what you did, so it might be something else. I would eliminate that possibility before I accuse this mod.

You can check why your registration was denied.

One issue we are having with the board is that people come on and register a new account and then in their user profile they put spam links. They also post without a link ... then add a spam signature later. Both of those things are allowable even with this tool. Is there a way to easily mark new users as spammer from their user profile? Also putting users into moderation who add links to their signature and or anywhere in the profile

You can use the newbies manager to put them in a newbies group. That group you should make with less permissions, for example, turn off the ability for the newbies group to post signatures.

Sounds like an excuse...Does spam-o-matic deny registrations? If the spam mod
thinks I am a spammer then tell me why i would blame another mod for blocking
my signup to my own board?

Its like when someone hacked my completevb.com theme, all roads
are pointing to his theme URL, but rather then helping, his first advice
is to say its not his theme but another mod...all hacking url attempts
lead to his theme, so why would I think it would be another mod?

Same here, if this mod prevents registrations for whatever reason based on
stuff we do not really understand, then why would I assume that another
mod was the cause of my registration failure when it clearly stated that
I was denied because the forum thought I was a spammer...so why
would i think it was another mod then spam o matic? its not another mod,
spam-o-matic thought i was a spammer for a reason...and if it denied
me for that reason, then I can only suspect that it is not perfect and
may deny other members also...accept it, or not....

I really do not like the concept anyway that spam o matic shuts you down
without any real cause...a simple questions and answers will prevent
95%+ of most spam signups anyway....

If you are not giving information on why you were denied registration, then it will be hard to see what the problem is. You are not clearly stating your problem. Check your logs and see why you were rejected. Please do this first. Then you can expect people to try help you.

You do address one problem though: out of the box the messages to the user are pretty vague and can easily be interpreted as if the user is accused of being a spammer. I get lots of support tickets from aggravated people that have interpreted the message as such. In 99% of all cases their IP is blacklisted by SFS.

If users would instead get a message that their details are blacklisted by SFS, that thousands of websites use this third party service and that users should contact their ISP to resolve this, then users would not take this so personal. That would save a lot of support tickets as well.

My one forum apparently had allot of spam for a while, is there a way to run this against the existing members so that it deletes the members and posts that match spammers automatically?

The generic message is easy to change, as it is simply a phrase:

I have used the below, which is explanatory, and I think needed, so that an unintended victim understands why this occurred, and that it is being done in the best interest of the overall community. It may be a bit verbose, but when denying a registration, it is prudent to present the reasoning, for those that get caught up in this that are not spammers.

Also, make sure you set the StopForumSpam: Remote Expiry option to a reasonable time frame (e.g.: don't make it months).

Can you please tell me why the submit function in de admin cp profile editor has been removed?

P.s. Askimet and Stopforumspam API are filled in correctly
p.s.1 asked this question earlier but never received the answer

I echo this. That function was perfect to deal with new registrants who simply signed up (got through the mod) and were either sleepers, or homepage stuffers.
