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?
There is a specimen called "Forever Junior", and its normal behavior is to join as many bounties as it can, as well as spam the forum. There is not a limitation for this specimen as well as the rules are respected, he can spend its time in the Altcoin section and have a million in its activity number if desired. Of course, this kind of specimen probably will never rank-up.
