Many developers are turning off their comment sections due to scam attempts and fraud links regularly occuring on itch.io; it's been happening for months and the platform is yet to find a solution, and not all devs feel comfortable with risking their player's safety, nor have the time to actively moderate the comment sections 24/7 (myself included :( )
the best place for bug reports are on discord tbh, as this is the place where I actively check & chat with people!
