Wow... that is an unfortunate name. Yanno... 'cause one of the oldest/most popular porn sites has "Tube" and "Red" in it's name. I can just imagine the shock of all the grannies googly moogly searching for cute kitten vids and... well getting "kitten" vids instead.
As for the youtubes and their ads...
For ages just having Noscript and Adblock installed made it a pleasantly ad and problem free experience. Lately though I would get the spinning bubbles for an annoyingly long time, then an error message and THEN the actual vid would play (I can only assume it was trying to serve up an ad, failing and then moving on to the actual content).
Even MORE recently it would never get to the actual content and all I'd get were the spinning bubbles.
I just didn't use youtube for a while but then got to searching the issue. Now instead of just allowing youtube.com and ytimg.com in my NoScript settings it seems a new domain (googlevideo.com) needs to be allowed for the vids to play. After allowing that it seems I have been able to go back to watching all the vids ad free as I used to. I haven't really been doing much YT viewing though so perhaps my cunning plan isn't quite as cunning as I think it is but so far it works.
The site really has become progressively more annoying since the google takeover. Especially the stupid forced autoplay crap that needs to be disable every new session.
