The site is excellent in its design and functionality. The man who runs it, César Del Solar, puts the source code on GitHub to share with the world so I can get an email whenever he fixes something. I had to mark it 18+ because I am being over-honest. It has "adult" words in it (race insult words, sexual words, curse words etc.) in a word game context. It has the School Scrabble lexicon (OSPD) so students can practice their lexicon also. There is no sexual or violent or immoral context apart from using some vocabulary words associated with those topics. It simply connects to PayPal or a payment service to collect $20/year for membership or other donations. César is close to the Scrabble expert tournament community and has a good reputation. I would vouch for this site over Facebook since I don't know anybody at Facebook and this guy goes on Facebook frequently to talk about how much he wants to learn to win Scrabble and how much he hates when he loses. You can trust this site completely or I am a total fool. The one thing I have not done is try to isolate this site and try to look at all the packets, however.
