Youtube New "Video Spam" Filter or Not?

"Sexy videos" that were uploaded yesterday and today were all deleted(accounts suspended) within 45 minutes after uploading. This has never happened before. Has youtube made somekind of new filter which detects videos that use watermark with .com address in it or detects videos that have been extracted from one big compressed video?

Am i wrong/paranoic/did something wrong (i hope) or youtube has advanced so much that you can't post too many "same kind of" videos with long description and a lot of tags?

*i did everything very professionally so it can't be ip-s, cookies, flash cookies etc.

Any fresh info?

did you use obvious title and description i have tested this and i have uploaded sexy videos but used low profile words for the title and description and they stayed on for a few days

There's the possibility that you had bad luck and have been flagged massively.

Competitors, anti-porn flaggers, etc.

I wouldn't draw any conclusions based on one incident/day.

Even happens with other kind of vids.
Now and then I see a couple of my accounts banned in a row while other similar ones stay alive.
