Had over 1100 bot accounts sign up today alone. Not sure what their fascination is with our little corner of the internet, but the manual approval process is keeping them out for now. It's not a sustainable process though, as it takes time to go through and deny all of them.
Out of the dozen or so accounts I've approved recently, only one ended up actually being a spammer and was promptly banned and deleted.
I'd like to reiterate, never click on links in the forum from people you don't trust, especially users with only a few posts. Also, if you get a suspicious personal message on the forums from a new account that you don't know, let me know about it. I want to make sure they're not spamming via PMs as well.
Thanks.
