I am a leftist s obviously biased, but my experience with them in general has been fine, there are some trolls or stupid people like in every instance but i had to deal more with right wing propaganda and objectively false information from conspiranoic peoole than from anything terrible coming from them so far, to the point of having to block several exploding heads communities where they shared tons of missinformation abour queer people, vaccination and all that bullshit. That one is the harmful instance in general and not hexbear where most of their content are memes and some insightful discussion every now and then.
