Not everybody is skilled like you Apache
Some people choose to keep behind a bogey after quick-but-careful calculation. They know how much time they have to down their prey, and if the time is up, they break off and run promptly... but for the majority, judging if one is safe or not doesn't come so easy.. and at those situations I try to give out a check 6 call.
Really, giving a check 6 call when a bogey is within 1.5k range of you is not very useful for the untalented people like me

... and thus, I try to give most of my warnings a bit early.
I give a check 6 call, and a short explanation of the situation..(.. like "Spit 6 high, diving..." ).. and if he still chooses to fight despite danger, I just give it a shrug and go my way... no point trying to help a guy in trouble when he was fore-warned, and advised to break off to safety.

So, some of the calls you got might have been intended as a pure gesture

.. but still, giving out a fakey to go in for the kill yourself is one of the lamest things I can imagine in AH. Don't mind those dorks...
