What’s going on? Is SW glitching or…

Someone left a perfectly benign, pleasant comment on one of my posts. I went to heart it, but I couldn’t because apparently I’m blocked. Huh, thought that was a bit weird. Then in another post of mine there was an argument between 2 users, one agreeing with my post and one disagreeing. I went to heart a comment by the one agreeing with me, but it seems I’m blocked by them as well. I find it kinda weird that 2 people who seemed to have no issue with me would just block me randomly. I mean maybe they really did but I’m wondering if there’s some kinda issue with SW
