Anybody else get spam links on Facebook whenever you type words like "movie" or "film" in a status post? That seems to happen to me every once in a while when I do that, usually several times within a short period, sometimes I'll even make a post that includes the title of a current movie and get some spam link to that movie from some name I don't know. Of course I never click on them and always delete the comments as soon as I'm aware of it, but why does it happen?
Also, every once in a while, I'll post something, and get a comment from somebody I'm not friends with online, not following, don't know, and if I click on their name I'll see that we don't have any mutual friends and they live far away, and it's often with recent posts and comments that I'm not particularly pleased with (though usually I don't think they're bad enough for me to report them, and it's not like the same random people I don't know keep doing it). I thought only people I've accepted as friends on Facebook could comment on my posts (or maybe mutual friends if it shows up in their news feeds when a friend comments). I have thought about asking these people how they've seen the posts, I almost feel like asking if they're stalking by looking at my pages and commenting on certain posts (but if they comment, they're letting themselves be known, so I don't think that's stalking). I have a feeling some are trolls. Should I ask them or just act like they haven't commented at all?
