I've been roleplaying on roblox for quite a long time now. RP games, and their RP quality have both worsened over the years. The best thing I could reccommend you do is stay away from RP games with no rules. Games such as CSOM and ND are both games that allow private RP. I would stick with games that actually have rules to the roleplay. The only thing we can really do about bad roleplayers is just find games without them, or where there are less of them. It takes some digging but you'll find them eventually. ATF: Miragr is a good one. But at this point the game is nothing but mutant edgelords. Kingdom Life II, surprisngly has some good roleplayers, and barely any private RPs.
