A friend of mine got a 30 day suspension and a bad record for 5 years
on his solo cross country. Personally, I require my students to use
flight following in case they get into the class C by mistake.

He busted the airspace so there wasn't much to contest. I'm sure if
he'd gone to court and lost the FAA would haved asked for at least 90
days (this is typical, 30 days now or make us go to court and we'll
ask for 90).

Robert,
Nothing to contest?????! What???!
There is always something to contest.How strong was the FAA's evidence?
Who was this pilots attorney?When in doubt, file a NASA report.Just
because the FAA ask, it doesnt mean you have to take a violation.It
also doesnt mean there will be a greater penalty if you contest a
certificate action. As a CFI you should know this.

If he has flight following he's not violated any reg.

I hope you dont teach your students this! You cant enter class B
unless you have a specific clearance to do so.AND, just because your
students request flight following it shouldnt mean that they can
meander into any airspace they wish.What do your students do when
flight following isnt available?Your attitude is kinda dangerous.
