I wouldn't mind ads if,

1. They didn't repeat the same 3 ads every few minutes on high ad videos (No It, I will not take it >:c)
2. Moderated and removed obvious scam ads
3. Remove ads that are disgusting or clearly inappropriate (I have seen some stuff that could be categorized as porn in YouTube ads and no I do not allow them to feed me ads based on my interests)
4. If ads were still not being actively used to spread malware/viruses (not sure if this happens on YouTube at all but I would rather be safe then sorry)

Hmm I will consider it. I tried some user styles I found but didn't like them as they were hastily thrown together. I have messed with CSS before.
