I think the limits were put in place because of the non-Japanese propensity for spam. I mean, it's been noted that the Japanese forums have by and far less threads, less posts, and more liberal use of the Like system. Conversely, we have three threads right now on the front page all saying effectively the same thing. And people are prone to repeating threads just to have a thread on the front page that's 'new'. We kind of did this to ourselves because of our desire to all be special snowflakes. I'm fine with the limits, it's rare that I ever run afoul of them.
