The kind of accounts that parrot Reich-wing disinformation, lies, slurs, or crap like, “ḟüḉḳ Joe Biden” or, “ḟüḉḳ Trudeau,” mostly they are idiot troll accounts, or worse, actual hostile-state propaganda instruments.
When you engage with them, you legitimize them. In some cases, the operators get paid by the reaction and the reply. That is why so many of their posts and comments are just infuriating kicks to the hornet nest.
If you see someone type some Con shit, instead of hitting reply, which is what they WANT you to do, go to their profile. Is it mostly empty of the banal traffic of a real person’s life? Is it full of posts that were taken down because they were hate-speech? Is it full of obviously inflammatory disinformation posts? Is the account mostly empty, few if any friends, or photos etc?
If so, don’t waste your precious fingers even giving them one. Report them if appropriate, then BLOCK them. If they get too many blocks, they will have to dispose of the fake disposable account and start over. That way at least you made them jump instead of them making you jump.
