Admins and moderators on this site deletes your content simply if they feel like it. It's not run by professionals following rules, but rather they make up the rules as they go along.
My comments were deleted by one of the founders of the website for referring to him banning the use of the phrase "ad-blocker". Apparently you're not allowed to talk about the words they ban, nor "ad-blocker".
Commenting on their decision to delete my harmless comment then resulted in a warning on my account reading:
"Reason: Perpetuating personal arguments publicly.
How to fix: Stop re-posting conversations via screenshots, text or links, and avoid mentioning the usernames of others in a negative context. If you have an issue with other users, please either Block them from contacting you, use the Report Abuse button, or report to local authorities if necessary."
