If I’m correct it’s against the site rules to call someone a troll.
I have found there are some users who just comment on posts to troll. They respond in various threads in an attempt to aggravate and derail conversations. This happens to me and I feel drawn in.
I think it would be useful to identify someone as a troll. The way things are we need to engage with users assuming they are good intentioned. I feel just being able to label a user a troll would limit this behavior. Just being able to say it would end a lot of the derailing IMO
