Irrelevant slurs.

Influencing public perception by mass up-/downvoting is not a right-wing only strategy, it's in every extremists' arsenal.

Possibly the person who created an account literally named "communist" to comment on this.

Everything is so fucked up now that fascists are bad but communists are good.

I see unsourced information (inciting violence; whether it's true or not is not my point[1]) and irrelevant information (what does it matter if they're communist, the implication being that it does, and that they're getting what's coming to them). The lack of a disclaimer otherwise also may be seen as tacit approval of the police raid.

[1] This appears to be site in question: https://augsburgfuerkrawalltouristen.noblogs.org/ (German). At first glance it seems pretty tame. Maybe they changed it, I don't know. And of course the relation to raids is tenuous.
