I think the constant advertising is a different kind of threat than being stalked by a chatroom random on AIM, though. And I can't really say which is "worse".

I think the constant advertising is a different kind of threat than being stalked by a chatroom random on AIM, though. And I can't really say which is "worse". The advertizing is legitimized and normalized by the entire system, from the content creators that make videos that are nothing more than thinly veiled ads, to Google's inability/unwillingness to properly moderate content.
