I am sorry, I did not comments caused such a problem in storage space.
if each user gets an average of 10 100% votes a day, there is then an expectation for each user to generate about 10 posts a day (i think these mostly better be comments as images and higher content uses more storage space). I don't know, just thinking out loud. this is why also equalizing voting power is dangerous, because the place will be run with voting bots.
