Absolutely. Some aspects are unavoidable, being an anonymous thread based forum, so trolling, flamebaiting, brigading and the like happen here just like Reddit.
Luckily on Lemmy we do have workarounds to some of these issues. You can join instances that disable downvotes for people who are bothered by it. Federated, publicly visible moderation has its ups and downs but at least you have all the information and you can decide to move to an instance where you fit in better.
