Some points/questions:
First, why does it matter for you how others get their mats and credits?
To me cheating implies that there is competition of some sort and others are illegitimately gaining an advantage, but in Elite outside of PvP, where it's mats that matter more than credits, I don't think that applies.
Secondly, the slf exploit is effectively the relog mechanic that is a function of the way Elite has been built unless FD intentionally build it differently (such as core mining.)
People have been relogging at sites like Dav's Hope and Jameson's Cobra for mats since they were found and FD have allowed and tolerated this. The only difference is that, as far as I'm aware, this is the first time that a high profile relogging can be used to (almost) directly generate credits. If you were to remove credits from 'cheaters' then you'd have to remove mats from every Jameson Cobra relogger as in terms of game mechanics they're identical.
Finally, this exploit is only 1.5-2 times more lucrative than other existing possibilities such as mapped mining.
The game has long been in a place where a new player can be in an Anaconda inside a day, and the Trader Elite rank can now be obtained without even doing a single trade run

The game's progression has been borked for years in so many ways and this is just another example. It's something FD have done deliberately as they introduced new mechanisms and they appear to have given up on any idea of earning balance.
I've also given up on it mattering and just enjoy my own gameplay in my own way.
