Yeah, moderators do receive a payment based on a custom algorithm which isn't disclosed to moderators or the public. Although, we are not employees of Bitcointalk.org. Theymos has to manage the current staff, and I'm sure he's got other things going on in his life also. Therefore, moderators will only be added if its shown that they're required, and the best way of judging that is by looking at the state of a section, and how many reports are being made.

Who knows existing moderators, and global moderators might be able to pick up certain local language reports. For example, I can read some languages okayish, but writing in them is a different story. I believe hilariousandco can speak languages or at least understand other languages aside from English, but don't quote me on that.

There's going to be multiple factors involved in appointing someone moderator, and I'm sure if the need for a moderator was clear then they would get appointed.
