The spam is getting out of hand. Without first post moderation, people are just carpet bombing this forum with affiliate links or promotional material. Even if you remove the offending posts within a day, site visitors still end up clicking through links on these posts.. so an economic incentive remains to keep posting over and over again under new names. (Remember that exness spammer?) There are plenty of ways to moderate first posts of new users in vB.... if you don't need any special filters and just want something basic, there's a built in option in vB without any mods/addons. I don't understand why it hasn't been implemented yet. Frankly, I'm getting tired of clicking the 'complain' button nearly every single time I visit the site.
I forgot to respond to this request but the first post moderation was implemented about a month ago, which has helped a lot with the spam. Just wanted to say thanks and circle back around to let you know it was done.
