LJ problem

Recently I've had a problem with comments showing up on ONE old post I made to one of my neglected comms almost a year ago. It seems that every day for the past few weeks I've been receiving some really strange comments, some in foreign languages and some clearly advertising different things. I thought it very odd that they would ALL be on the one post. I'd get the usual messages in my e-mail inbox showing 'Livejournal Comment' and only ONE of them was a legitimate and very nice comment. I've had no choice but to delete the post entirely. That was a shame because it was full of nice pictures and things, but I just cannot stand getting any more of these weird comments in my inbox. When I went to the post to check it out, LJ had marked 4 regular comments and 82 'suspicious' comments but didn't do anything about it--I guess there isn't much they can do--and so I felt I had no choice but to delete the whole post.

This kind of stuff makes me feel bad, but I suppose it's rather normal for the internet. I'm going to friends-lock all my posts from now on, though. :(
