there's already a very slight delay in posting to post showing, I don't think that increasing this by a second or so to scan content will be an issue.
that's basically what I'm saying we need, a comment filter.
but instead of one that take the words "buy viagra here". and replaces it with "buy ****** here", we need one that displays a message saying your comment could not be posted, please read out AUP.
it will take time... and just like most swear filters, determined individuals will try to get around it. and when they do, all we need to do is add another keyword to the list,
so we end up banning the word
shit
SHIT
Shit
5hit
Sh1t
5h1t
etc until we've got a list that can't really be compromised.
as already said centralcomputers dot com could be a prime candidate for this list. their not a big supplier, just a random spammer.
as far as I know no member here has or will buy from there, and should anyone ever ask why they can't link to that site, or why if they try they can't post then we can all tell them it's because they spam the crap out of forums and non of us would touch them with a proverbial barge poll.
a double whamy, we get rid of spam, and we make it known that when/if you spam our site we won't do business with you, and actively advise others not to either because of your bad business practices.
I can't imagine anyone asking for advice on say trainers and listing several brands in one post, so perhaps if the filter could look at brand names and frequency on a single post it might be able to make an intelligent decision.
