warning system:

but in less than a day this thread was removed.
Basically, the thread mentioned that some older members were getting
preferential treatment over newer members, and that the yellow/red
card warning system was silly.
A moderator responded that they once used private warnings, but users
were ignoring those, so they went to a public warning system.
This appears to be an outright lie. If a user was ignoring warnings,
that implies the user continued his bad behavior and received more
warnings, which would have caused him to be banned.
No other racing sim forum uses a public warning system, so it's apparent
the problem is with RSC's moderators and not it's members.
