I hope someone gets an answer for this, i was a jnr member before i just woke up to see that my stuff has changed to Newbie without any reason from the moderator or admins, is this not illegal?
Any advice how i can get myself back?
There is nothing wrong with your account neither did anyone do you harm, your posts were deleted and as a result reducing the number count of the required post and activities for each rank, this shouldn't be a problem, once you're able to continue posting, but this time i will advise that you make a quality one that could escape being deleted by the moderators.
