Just have logged back in (computer, not mobile) and there are five (5) pop-ups ads on the screen, whose total screen real estate is larger than the forum text (content) box. This is serious over-kill. And, frankly, if I were an advertiser I wouldn't want my ad having to compete with four others for viewer attention.
Conveniently, this is the off-season, so I can check our for awhile and not miss much. But if this isn't remedied/mitigated a month from now, I'll be done with Intermat, the value won't outweigh the annoyance. And, from another poster supra, if enough viewers bail then the advertisers won't support the site to the same degree, so the current approach is self-defeating.
Please reconsider your advertising changes.
