[DXBase] telnet filtering

[FireBrick]

One of the unfortunate results of the internet cluster system are the idiots
who flood the system with semi flames, intentionally phony spots.

Mini announce/full firefights have become routine.

DX Net members who spot each and every net station.

But the worst are the lids using profanity in their firefights.

As far as I can tell from studying the three major Clusters softwares, there
is very little that can be done to filter these types of behaviour.

set/noannounce eliminates proper announcements.
even set/nodxdedx has it's disadvantages to some.

I can see no way around this problem without program specific filtering
options like you can set in your email client to bann spam.

Actually I think 'spam' is a good analogous term for this problem.

I never considedred myself thinskined, but I find some of the Cluster Crabs
to be ruining my enjoyment of the hobby.

Sorry, down from soapbox.
