Get with the problem gramps.
Useless comments on steam workshop are the hottest thing right now!
But in all seriousness there is probably some site pointing out workshop pages that seem funny and then people click on the link and leave a mark. It’s like demanding to be included in a screenshot when someone f’s up bad on certain Mesopotamian mosaic boards. It’s just a short dopamine injection. Don’t mind it.
I’d simply decide that “people are idiots” and moved on. It is possible that there’s some “steam achievement” associated with comments and they’re trying to get it.
