This is probably a pretty spiky topic, but what would the downsides to doing this be?
I personally think that 2 is a bit too restricting, and i usually hear of people not using Danbooru because of this huge limit.
The usual argument i hear about this is that it acts as "incentive" to purchase Gold and Platinum. Assuming that is true, if the limit was raised then it would mean that less people would be pressured to buy Gold. On the other hand though, more people would probably use Danbooru, which would logically bring more income.
If the argument gets too heated feel free to lock this thread down, this isn't supposed to be a provoking question, just a suggestion for a quality of life improvement to new users.
