Have you ever deleted a comment? What would make you delete a comment?
Let’s just put this in the context of my blog only…: NO.
I haven’t got a blog that is established enough to have an influx of comments, so I haven’t had a need to really moderate comments or even delete comments. I think that it would take quite a lot for me to delete somebody else’s comment… It would probably have to be quite offensive to warrant being deleted, and even then, if it was quite offensive, and that person felt okay to actually post it in the first place, then I would have hesitation whatsoever but to respond and pretty much just put them back in their place. THEN I would consider possibly deleting it.
