That must be a matter of balance; If one MOC is easily changed to represent various different prototypes, they might only warrant one MOC entry.
If a lot of work is put into the modification, then surely it deserves its own particular entry.
Lastly I dont think there is such a thing as "too many MOCs entries", as long as it is not an automated posting. You should be able to post as many MOCs here as you are able to construct in a day. If you want to post MOC's from several years back, maybe you should consider spacing them out, so as to give the public a chance to digest each one, and not miss out on any.
Just my 2 cents... Permalink
