5. A malicious/obtrusive advertisement has appeared while browsing the site, please fix this?

First of all, a clarification must be made: the staff does not have any direct control over the advertisements that are displayed on the site. We also do not see any advertisements ourselves due to the administrative ranks we have.

All the advertisements are managed by a separate and dedicated Ad Team, to which we send a report every time a bad advertisement is caught - to have it removed from rotation. And for us to be able to report these bad advertisements we need detailed information about them saved and sent to sneeza@outpost.gg.

The information we need to be sent us are:
Company name;
One or more screenshots of its display area;
Ad Type: audio, redirect, pop-up or malicious (software update, installation, etc);
Source code (if possible);
