Perhaps something akin to a Discord server? I don’t know if BeamNG has an official one, and if it doesn’t, I really don’t think it should. An official Discord would be far too much work for the Devs and Mods to manage, and would create too much liability. However, if some users wanted to create their own Discord server that was not officially supported by BeamNG, users could join and post all the stupid stuff they want, thus keeping it away from the BeamNG forums. TLDR: If you want to do stupid stuff, set up your own Discord or something.
