Im a member of a forum that I rarely visit due to the fact that it has full page ads.. I will be browsing around the forum and randomly I will get hit with a full page ad. It takes a few seconds before the Skip this ad button becomes visible so I have to look at the ad.
Another forum I'm on makes you view a thread with adverts in it before you can see the rest of the forum. You get a message like Forum Locked. You must view this page to see the rest of the forum. then it takes you to an thread full of adverts.
How do you feel about forced ads?
Having ads as just a banner in the header or footer is fine but forcing me to look at them is a HUGE turn off.
