Hi, I have a website (classified ads) website developed in Wordpress with a classified ads theme. It's doing pretty good but the problem is that I get loads of spammers who registers as a user and then post spam on this classified ads site. I have been going in to remove those users and their posts and that's a lot of work. I was wondering if anyone know of a plugin or setting that can force users to complete a CPA offer or the like before they are allowed to post. This should discourage spammers and for those legitimate posters, I will leave a message explaining that this is how I am able to maintain this classified ad site to be free. Anyone know of a plugin that can do this? Or any other bright ideas? Thanks!
