When people favorite one of your submissions, do you thank them on their front page for each time they fave one? Do you only thank them once? How often do you think thanking them is too much?

For me, I tend to try only thanking a person for a fave if a previous comment of mine isn't already on their main user page. I don't want to clutter up their page with multiple comments from me, so if I see that I've already thanked them once, I don't make another comment again until that previous comment is no longer there.

But yeah, just curious how others handle it.
