I didn't realize there were certain ads the site wanted blocked. I've seen a political ad, too, and a really disturbing child abuse one that really bothered me so I avoided that particular forum for awhile until I noticed it wasn't showing up.
Are we to submit anything we find inappropriate or are there just certain types (like political) they want to be notified of?
To get the URL do you need to click the ad and submit the address it takes you to?
