Welcome and enjoy yourself! Most important thing you should know before going all-in is to have fun, and remember this is a game. I know it sounds retarded but a lot of people here forget it's a game and self-indulge into all sorts of degeneracy and/or weird behavior. The people who claim they have been harassed (at least from this post, Hex 100% has) have truly been harassed by certain members of the community who no longer play as much. These people who have targeted users like Hex (even if sometimes Hex can provoke this -- it is still wrong) find enjoyment in making your time here as troublesome as they can get it. Luckily for you, there are new admins who will see this for what it is and acknowledge it rather than make excuses.
TitsRP at core plays moreso like an MMO in terms of how you can grind and consume content as it's released (peak updates don't happen as often anymore but the game has a lot to offer with updates here and there from Rubik). You have a ton of stuff you can do but burnout from playing too much is a real thing that consumes us all when we used to play all the time -- or still do.
TLDR: Just enjoy yourself and just like any other online community, you should limit how much personal information you give out and place onto your profile.
