While I don't discourage reading the JP forums I also would suggest to not look too deeply or to believe everything written.

People in our own thread are misunderstanding eachother and we all speak English and just like this thread, there is wild speculation and imagined scenarios.

... and truth be told, it can be considered rude if one does more than that but if you insist on posting in there try to be respectful.

They have no actual right to stop Non-Japanese people from posting as long as you put genuine effort into attempting to reply in Japanese, however that does not mean they have to reply to you or anyone else. In any online discussion there will always be someone who is looking for a reason to voice their displeasure and a non-native speaker is unfortunately an easy target.

Take what you read with a grain of salt and if you insist on posting there, keep it short and simple and ignore anyone who appears annoyed or aggrivated by your presence.

If anything, unsettled JP players tired of all the non-native Japanese posters would likely increase the priority of the issue, but... don't give them a reason to hate non-JP players.
