Roxy, I've already voted several times. Give 'er!
Smudge, I manage over 10 websites and most of those
spammers that sign-up up here are from China. They
are human and take the time to sign-up. I have most of
that country blocked from viewing my sites. they get
a 403 page - sometimes if you get a "403 "Forbidden:
You don't have permission to access this server", that
means your IP address has been blocked, purposely.
Gets more complicated, that's generally it.
I've managed a a forum and I can spot them easily,
and would delete them immediately. For example,
'Tecoisle' is a spammer and is still here. It would me
a few seconds to delete him.
I've sent J.O'B emails on how to block IP addresses
to forward to his web people. I'm an Internet
Security & Privacy expert as well, (that's why I don't
use google, very creepy, I use startpage).
I asked 'masteradmin' (which isn't John) about this and
to delete a spammer, and he didn't answer, plus, he disabled
his PM so I cannot send him messages, so I think John should
fire him promptly.
So viva is an easy target, unless John assigns a new 'masteradmin'. Keep voting.
