I mean something to realize about forums is that the majority of a games player base will NEVER visit them and of those who do the bulk are going to be people who have an issue with some aspect of their game experience.

So by their nature forums and by proxy the perceived community are going to tend to slant towards the negative.

The inverse is also true tho not always as frequent but usually equally zealous in the form of fanatical praise, which is arguably just as toxic.

And if we think we've got it tough trying to filter through all that, imagine being the developer. On one hand having people saying they hate everything you do and on the other people saying you can literally do no wrong.
