set max_user penalty back to 100, or 80

set max_user penalty back to 100, or 80

as 200 is a sure not proofed maximum that I have even not seen at the fork of Multicraft 2.0.0
Max seen or tested:
* Multicraft 80, what mean set 100 with penalty at 81
* Minetest 5.2.0 on my server, got 64 gamer in with all in afk zone, lag 1.0, mean set max to 80 = penalty at 65

The max of 200 is misused to offer something that IS not there !
There is and will be for some time no hardware or low mod server that can really hold 160 users, what mean no malus

It is misleading gamer about the server options,
and also an affront against the server owners that use reasonable max gamer on there servers as of their experience what server can really do.

After Server might proof more, wen can rise up ... but 200 is a LIE !

No file, test, or entry point is named. Locate the code that defines or applies the max_user penalty, then inspect existing tests or validation around the advertised maximum; done means the configured limit and penalty no longer present an untested maximum of 200.
