It's a private site Vlad, are you so dense you cant understand that? It's not yours, not mine, not anyone's but Paul's. If he decides to flick the switch and empty the database daily cause he feels like it he can. it's HIS. Just like facebook owns everything that's on it, even if it's personal information about people. You sign up you agree.
Just to play the devils advocate here.... using your Facebook analogy.
Facebook offers bunch of games on their page. Free yes. You pay for Facebook coins to play those games to level up or whatnot.
Then Facebook removes those games you paid Facebook coins for.
You'd be cheesed right? Sure its their site and its free, but users did contribute time and money.
-- note --
not griping.
glad that Paul apologized and is rectifying the situation.
Good on Paul for that.
