Some general tips when starting in the PvP server; join a clan, try to get some funds, dont spend too much on ships at the start of your PvP career (because you will get sunk many many many times), try opening outposts at freetowns if you want 'quick' action, but most importantly is try to enjoy it .
And in regards to toxicity, I dont experience the toxicity as explained above^. Some people do have a toxic mindset, and ganking (massive outnumbering/overpowering) someone happens but that's part of the game.
