Firstly, this topic is posted in the wrong forum and belongs in
Meta. I don't think it's unfair to say that if you can't even post things in the right part of the forum, you shouldn't be eligible to attain higher ranks.
Secondly, the forum has a big issue at the moment with low-quality posts. This has nothing to do with your IP or location. The new rules apply to everyone equally. If you haven't earned any merits, you can't be a Jr Member anymore.
Read this thread and all will be explained. In future, try to search the forums to see if there are any threads about it already.
