but if the level of discourse had an upper cap which easily contains the habits of a semi-active user, then I generally welcome it.
Again, your commenting far outstrips that of a semi-active user. Perhaps you should be advocating for a comment limit based on the average user as well.
You should probably advocate for a post limit based on the average poster too. Wouldn't want it to be unfair, after all. And posts are MUCH more visible than votes or comments.
I have a feeling that this impacts largely a minority of one.
It was geared towards the muzzling of ten 'top' users (10, mind you, is some ~2% of the daily users of Piefed.social to begin with), but under the presumption that their votes are evenly spread out, day-by-day.
In reality, most people aren't on the Fediverse every day - they come in, participate in a discussion or three, and then might not be back for a few days. So it's easy to hit the limit, as it is a daily limit, simply by being active in a discussion.
