Remember about the Pareto principle: roughly 20% of users is probably responsible for the 80% of the content. This 3% is quite a lot in this context, especially considering the active people are probably much less complacent in this regard.
And how much % are bots, tho? I know that prior to and during the 3rd party API announcement I got so many requests from OF promoter bots that I suspect that Reddit will be the epitome of the Dead Internet theory
