The only sustained, inappropriate effect this is likely to have is probably just the Most Favorited - which kind of illustrates how bent that particular statistic is, but as a week or two passes for a given person, it's resolving itself.

If this activity grows to the point where comment counts are regularly showing up in the Most Commented count, then I see that as normal use of the gallery.  If things really grow that large, if it really bugs the regular dominators, they can be brave like Drifterlee is, she's a great example to everyone.

Most Favorited Images is terribly, terribly unlikely to be significantly affected by this, nor is Today's Top Rated (most of us are not rating most of these images).
