wtso.netは安全ですか？

It is neither safe or unsafe. It's kind of in between. It really depends on how you view it. If you have an ad blocker, it's safe a good amount of the time. I wouldn't trust it 100%, though. There's the occasional popup on a video player that has a virus, also. It didn't have a safe past, so be careful.

This is unconfirmed, but I can say that I don't trust it. Kpolulak is right, see past entry, and there are too many ads. That's not all, though - I'm not a member of VideoBB, and never had this problem before, but it would seem that I have a nearly undetectable trojan. It tells me I watched too much and stops me. I refresh, but guess what? It STILL knows how much I've watched....Spyware? Virus? Trojan? Who knows.

can watch most episodes in fairly okay quality, but the site is kind of ad-heavy and sometimes redirects to random sites. DO NOT visit without a good ant-virus/spy-ware program, because it is a bit dodgy. I stopped visiting the site after my anti-virus blocked attempts to infect my computer. It also hosts videos from many different places, and sometimes the places the videos are from are blacklisted. Not to mention the whole thing is pirating... D'oh!
