OK so we shouldn't be receiving any more spam PMs. I've put in two methods of blocking this:
If you're just a regular member then you can only send one PM every 5 mins.
SAU VIC, WA, QLD and NSW club members, mods, admins, traders and contributors can send unlimited PM's... the assumption here is that we've verified who you are so we trust you.
Also if your postcount is below 10, then you can no longer PM. This will hopefully weed out people who sign up and then supply the login to bots.
I'll run a few cleanup queries tonight which should remove the spam PM's from your inboxes if they're still there.
If you do get anymore spam PM's (ie after the time I posted this) please let me know, as it means the bots are circumventing the above patches.
Thanks for your patience guys.
