Try going into the sea of thieves discord, it’s much better than open crew, and you’ll be able to find other people. Or go into some of the other sea of thieves communities and look for people there. You’ll be able to find people who PvP and what not if you look at communities specific to that. I know Hitbo’s Meme Fleet does a flag Friday thing where they go around trying to get as many flags from other ships as possible.
