You are not quite correct in saying that the Polish section has no moderator. The Polish section currently has five moderators. There are three global moderators and two administrators who can handle reports on the entire forum, including the Polish section.
Thanks for clarifying. Personally, I thought that with the absence of the previous mod (malevolent) any reports are not processed.
Out of curiosity, is there any particular person out of those 5 that is responsible for handling reports from the Polish board, or can any of them pick them up? And how do they deal with them exactly? Do they rely on google translate etc?
All global moderators and administrators have access to the Polish section, so any of them can handle reports from this section. I don't think any of them are specifically responsible for the Polish section, although I don't exclude that there may be some agreement between them.
