People don't get access to the Erogenous Zone just by posting. There is no "magic number" at all. If a person is given access to the Erogenous Zone, that means that one of the mods has seen that 1) they are eligible (i.e. someone will not be even considered before a certain point) and 2) their posts are generally quality posts that contribute to the forum overall.
For this reason there are people with quite a few posts that still have not been granted access to the more personal and sensitive areas of the forum (Erogenous Zone, Exhibition, etc). So, I think that shutting down the Erogenous Zone periodically is unnecessary because of the work that goes into giving someone access in the first place.
Thanks for the suggestion though - they're always welcome
