"Not to forceful" on top of plug, is what I understood.

Here are photos of number 3.
It looks the same as two.
Perfectly centered. Not askew.

With the plugcap removed, you may try not to forceful tapping with a hammer on its threaded top.

I’m trying to make sense of this.
I can tap the threaded top with a hammer?
He’s saying: not too forceful (meaning not too hard, just rap on it). This approach can break the threads free from each other.

I would only use a long fat drift pin to hit the metal base of the plug, not the top threads as could be taken to the unlearned....they'd learn fast about busted plugs.

It’s nearly impossible to see where the
Pin is touching on the spark plug base.
So I don’t want to randomly hit the pin against
Something wrong by accident.

Besides using a breaker bar to remove this, I’ll just leave it alone until I need to remove it.

Worst case the head will have to come off and then you can have a good machine shop extract and do any repairs that might be needed.

A deep socket long enough to reach over the spark plug body but smaller than the hex can be sacrificed as a hammer extension to give the plug some good whacks to break the corrosion or bond the plug threads and head have.
Or some heavy pipe big enough to slip over the insulator or the plug

Meth addicts have taken to breaking spark plugs on MC or scooters to give them a chunk of ceramic to break car windows with to steal things out of cars. The ceramic will shatter a side window super easy..

breaker bar.

with an 18mm 6pt. deep socket, or the special Powersports steel deep socket(3/8" drive)with the rubber inside to cushion the porcelain.

Did you work on it with a hot engine yet ?

 Another thought is the cold freeze penetrating oils. I think they have liquid CO2 in the can along with the oil.
