Suggestion to combat Mentors intentionally inviting RMT Advertisers

[aesteval]

I actually don't bother blacklisting them unless I am going to be where they are spamming say channel for a bit, and then I remove them later since keeping them blacklisted only ends up wasting space on that list. The only thing I do in response to their spam is report them.

As for when they get into Novice Network, they advertise once and leave each time.

The fact that you don't blacklist is not relevant. The fact that some people do and the location of both options is relevant - it provides a readily available example of how they're invited accidentally.
