Obviously as a newcomer, I haven't noticed any. I mainly spend time in the "General Football" and sometimes the "Bluemoon" section.
Perhaps the case is different for this "Off-topic" section or if theres a Politics section here that I don't know about, but still the attention whoring on this forum or other forums is incomparable to actual social media platforms like Instagram.
It also doesn't help that 6 or 7 year old kids can easily make social media accounts, whereas they wouldn't be aware of forums.
