Welll, their user was creepo, but it looks like all of their comments got banned luckily. But if you do see any offensive comments, block and report them.
I can’t tell you what it was (it had quite a lot of bad words in it) but they are going around commenting offensive stuff on random posts, so if you see them, just report and block them.
Don’t worry I wasn’t saying your comment was offensive. Someone commented something on this post that was very offensive and I deleted that comment before anyone saw it.
