Two of the examples you posted aren't exploits, on the contrary, people who die more than once to one of those stunts should git gud, seriously.
1) anarchy starport shooting - solution: fit proper shields, cling to the hull of the starport, don't speed, don't shoot back.
2) ramming in black cutters - solution: watch your surroundings, don't let yourself get rammed by a cutter (rammed by a cutter of all things, really??)
I used the term as a verb, not a noun.
Exploit
1.
make full use of and derive benefit from (a resource).
Sorry to drop a definition on you, but I wasn't saying they were using an exploit. I said they were taking advantage of a game mechanic. In this case it's the ability to bury themselves in the station structure and shoot at ships entering the mail slot, hoping you shoot back and hit the station. It's not against EULA, but it doesn't feel like real gameplay, more like some fortnite level lulz attempts.
Same with ramming. Easily avoidable, but if you don't want to be in an instance with this kind of annoyance (since it serves no gameplay purpose), you can either block them or go to a different mode. For some players, the difference between legit CG suppression level game play vs griefing for lulz is indistinguishable.
I'll agree with you that pad blocking is a problem at the moment, both by blocking the pad, by hogging the pad and by NPCs.
Still it can be easily avoided because your docking timer is usually longer lasting then the docking or undocking timer of anyone "luring" you into this trap.
Also, reentering supercruise is a thing, as is instance-changing (which I do when I have a NPC block my pad - by switching to solo)
Sure, a lot can be easily avoidable. Why should anyone go the extra mile to do so just to provide PvP players with content? That's the point. PvP players should focus some effort on griefers who drive players out of Open which actually thwarts real PvP ability to suppress a CG, since it will be done in Solo or PG. Instead though, there's this really grey area between PvP role playing and flat out griefing, with some folks appearing to cross back and forth between the two - any excuse to salt collect since perhaps the game play is boring to them otherwise.
I don't understand why "git gud" continues to be offered as a rebuttal to these things unless people are simply ignoring the history of this game and how it hasn't actually motivated people to spend more time preparing for contact with the other gameplay styles.
