Re: What do your spam signups look like?
I have had the same issues as you all these summer.
Since approx. 2 mounth i have nomore fake user or fake blog. And no spam too !
I erased daily and manually all spammer reference in my DB. Mail adrress, blog content, names and so on… An endless job with no success at least. And i don’t use Askimet. I can’t explain why (or only in french), but i don’t.
I’ve installed wp-spamfree (who blocked 45 spam comments since i installed it in july), invisble-defender (who blocked 76 spammer in the same period) This is really less
I use also wp-ban, here i have given some ip ban’s instructions, banned some referrers like these:
and some wildcarded user agents like zhanglingjuan*
in my htaccess i have this, wich is very powerfull(i think it is this who reduced mostly my spammers)
Test it and see in your log file how many “libwww-perl” call you receive in a day and see what is in the url. You will stunning !
