Said it before, but I think that politics is the problem. Couldn't count the amount of times I've come on this site only to instantly hop onto another as soon as I see Trump/Democrat threads. Shit's exhausting and divides everyone, and when one side dominates discussions, anyone with opposing views is going to go elsewhere.
Perhaps if there was a request form to access politics rather than just having it publically open? It's not really a forum for constructive political talk. It's mostly good as a place to blow off steam on the low intelligence racists, outrage culture MRAs, and culty fanatics that skulk around in there. But it is also a completely off-topic location that probably shouldn't be visible to regular and new users, because (while it has its uses) it is the ugly side of VGchartz.
I think the forum has its uses, but it should be a gated community. The place is shameful to show to the public, and I can see how it would alienate and drive away many.
