My website (http://www.progressiveomaha.com/tikidir/ running Tikiwiki 5.1), has been acquiring dozens of new users per day recently. However, they rarely validate their email address; also, a number of them are from fast cash locations in the UK. I've disabled the tell-a-friend utility since I also seem to have been reported as a spammer.
Is there anything else I should disable, change or be aware of that might be allowing spammers to use my website? I've been able to get myself unblocked in the past by talking to my web hosting service, but I want to be sure I've covered all the bases before I do that.
Thanks for any help.
