Your spot on in your understanding despite the question being a bit confusing for which I apologise.
My question was to know if there's a maximum activity level for a Jr member without any merits as stated in title and in the body I expanded it into additionally include a personal opinion of what I felt would be ideal if there was no specific rule regarding the matter and wanted to know if anyone else thought the same?
I don't think it would be a good idea because there are people that just come here to use the forum to talk to people and they have no interest in getting merit or ranking up. I don't see any reason to punish people for that. I suggested that they should not be able to have signatures so they can't get paid to post as an alternative solution but that doesn't look like it will happen either.
