What do you do with an answer that has nothing to do with your post?

I have had the occasional response that was posted on the wrong discussion, although I cannot imagine how that was achieved. In those cases I have relied as normal and mentioned the error. As for totally unrelated responses, I would reply with a question mark.

I usually try to explain my main point that will helps the reader to answer base on my discussion

Yes, I think we have all had that at times. It isn't surprising because some people on here don't have a firm grasp of English,,other times people take one small segment of the post and comment on it..which is a bit annoying,,but it is what it is..some comments I just don't respond to.

If it's an opportunity to have a conversation then I simply answer and try to start one.

It happens time by time, I ignore those replies.

Sometimes one loses one's way in a comment thread. If I don't understand a comment, I ask, "Are you talking to me?" or something like that. Sometimes the puzzle is solved, sometimes it isn't. In the latter case, I move on.

I usually ignore them. I will comment and like everyone elses but not that persons.

I have learned to ignore them. There was a time when I would comment and ask what they meant exactly or sometimes I would say, "I think you haven't read what I've written." But I think the best thing to do is just ignore them.

I also ignore them.

I'm with JJ. I don't comment on them.

I take pity on those who wrote them and just respond with a quick thank you.

I get that type of comment every now and then. It is so odd to get a comment that has absolutely nothing to do with what is contained in the post.

If it has nothing to do with your post just ignore it. Not sure if there is an option to delete a comment. Sometimes, I find that the person either just reads the title and comments based on that or just leaves a comment for the sake of leaving one. Someone responded to one of my discussions with a question to which the answer should have been obvious had they bothered to read the actual discussion.

I usually just ignore them.

If they really bother you then you can delete them.

Nothing you can do it with them except ignoring them that's what I do.

You can usually tell the difference someone didn't read the post and is just looking for a place to draw attention to themselves and when someone read but really didn't understand your point. I usually respond to the latter, maybe with more explanation, but not to the person who didn't read. They are just trying to get attention at your expense.

It hasn't happen in my discussions yet, but I surely will have those type comments too sooner or later. I think you did the right thing, just ignore It.

Don`t know why someone do that. It happens to me to read the discussion and to have nothing to say. Better leave only with a like than comment something not related to the post
