We really can't help but notice them. They seem to be overrunning the site. Without moderation, they will take over and eventually drown out Blurtit.
Some users use Blurtit to advertise their websites, their groups, Facebook andTwitter page etc. Did you notice it?
its annying when they're inm your face about it and its almost like spam but i don't see an issue if they're just posting links on thier profile page
