Are these two PSU/PSP2 sites 'safe to visit'?

Hi i've been crawling, errr marching all through cyberspace & found some interesting PStar related sites. Are these safe to quote from & post links to on Pso-World?

I like to learn. Don't want to get in trouble for posting and bad sites, ever.

Any site links that promotes private servers or cheating is not allowed on PSO-World.

If you have any further questions about what is appropriate to link to, send me a private message.
