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.

Your Registration Request has been denied, due to your IP Address, Username, or Email Address being listed by the <a href="http://www.stopforumspam.com">StopForumSpam.com</a> anti-spam engine.<p/><p/>
The StopForumSpam.com service monitors and tracks spammers, worldwide, and lists their varying details within their servers.  Should any of your details match their database, this will result in registration denial.<p/>
In addition to StopForumSpam.com, we also use the <a href="http://www.akismet.com">Akismet.com</a> service as well to monitor and block spamming activity.<p/>
We would respectfully suggest that you either attempt to use another email and/or username, and see if this resolves the issue for you.  If it does not, it means that your IP Address has been tagged as a spammer, and this needs to be resolved via your Internet Service Provider.  We can assist you in getting this resolved.<p/>
<b>If you are still having troubles, please use the <a href="http://www.YOURFORUM.com/CONTACTLINK">Contact Us Link</a> and we will get your account setup for you.</b><p/>
We apologize for any inconvenience caused and truly want you as a part of our community.  The volume of spammer activity in recent times has driven these measures to be put in place, in order to keep YOURFORUMNAME from being filled up by spam postings.<p/>
Thank you for your understanding.

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