we / I do use social media for work (insta, FB, twitter) and occasionally attract negative attention from small groups of people, which is only really an issue on twitter, with conversations spiralling.
what we post is not particularly controversial per se, but can sometime split opinion (science related) with some messages and threads quickly spiralling to ad hominem attacks and name calling.
I usually do not engage, but it is difficult to see your work attacked (mostly because of misunderstandings, or nuances) without defending it. On occasion, people in my field join into the debate with petty unprofessional comments too.
I ve replied a few times, when i felt there was too much lost in translation, to try to create a conversation but it did not do anything else than fan the flames.
how do you handle this type of online conflict (social media is unfortunately a central part of how we communicate about what we do)?
