Frontier first took a stand against peeps pulling the plug when there was a fantastic opportunity to take long range smuggling missions to and from the bubble. Robigo was the best known destination, but there were a few others. The missions had massive pay outs, but they were dependent on not getting scanned. With so much virtual money at stake there were a whole bunch of shenanigans going on. Some players went out of their way to scan suspected smugglers, some greedy gits logged out rather than let themselves be scanned. There was no actual combat involved, but we all talked about 'combat logging'. And griefing. And nerf/don't nerf long range smuggling. (It got nerfed... ☹)
Before they updated the forum I could have send you links to threads about it. There are a lot of very funny people who used to post here, the internet handbags were fantastic!
Sadly, my search fu is weak, I can'tfind threads I was in, much less the mega threads the PvP crowd kept going.
I'll give you that they probably frown on it. I wouldn't ever do it because it's ...well...tedious to have to log back in. LOL
Check my previous post btw for an edit where I show you how your number of materials required for engineering pans out if you farm the materials specifically for efficiency. You way overstated the quantity needed to fully engineer a ship, by a massive margin.
