I mean, I get annoyed when I see the same thing posted to two communities back to back, but 5 is ridiculous and extremely poor fediquite.
Edit: Seems the poster is some kind of spam bot. As one commenter pointed out, they seem to have spammed this to any community with “music” in the name. And it’s more than shows up in the screenshot. A LOT more.
They posted it to any community that had “music” in the name regardless of if it fit. Either a spam bot or those annoying people who think more is always better when it comes to getting your name out there.
