Ads keep us online. Without them, we wouldn't exist. We don't have
paywalls or sell mods - we never will. But every month we have large bills
and running ads is our only way to cover them. Please consider unblocking us. Thank you from GameBanana <3
As CS PRO stated, this feature already exists. Also, if you're running into toxic users posting on your submissions, you should consider reporting them via support ticket before automatically defaulting to just disabling comments.
This is already a feature on the site. This feature can be enabled when either submitting or editing your submission by going to the Settings tab and changing the Comments option from Enabled to Disabled.
