It probably would still be a good idea to update the credits of every individual model as best you can. It's a bad idea to generalize the hard work of many people into just a couple of individuals or a "team/group".
That's the pet peeve that got me to spend all those times to name every single person and what they did in my Remod's credits, even then I still couldn't avoid naming just one person or a group/team, because the origin of the model that I acquired it from (be it a model pack, a mod, or something else) didn't have proper credits in the first place (just being either namedumps that doesn't list who worked on what or just putting it all on the guy who made the previous pack that the other pack was taking the model from).
+1. Actually, that's what i was trying to tell in the first place. Want it or not, you have to do it
The idea behind it is nice, of course, and implementation was funny (although, many members stated, that
their "avatars" were not serious enough). But i bet, that authors were not even put in account when this pack was making (but i may be mistaken)
By the way, taking the screenshots of all 156 models was not needed. It is not necessary, and admins were not pointing that out specifically
