Would making the cloaking action work for an unlimited amount of time, so long as the person hit the remain cloaked button every few minuets to force the cloaked person to remain at the key board and remain active to some extent be an effective balance measure?
Add in random timers for the continuation of the cloak to prevent botting even?
For example
Cloak is activated, count down timer starts (say 9 minuets) at 8 minuets 45 seconds you have to push the ((re-calibration control button)) within the next 15 seconds to stay cloaked and reset the timer to another random time, say 6 minuets 20 seconds, then last 15 seconds ((re-calibration)) must be done to continue maintaining the cloak, then another random timer is set say 14 minuets 12 seconds etc, etc,etc.
But if you miss the re-calibration cycle, your cloaks go offline for a full 2 minuets from getting thrown out of calibration.
The 15 second recalibration cycle could have an audible chime to warn of the CPU going critical.
After the 2 minuets is up you can return to cloaking again and restart the cloaking cycle until your mission is complete and you get out of Doge, safe log, you fall asleep or go AFK.
However, if the recalibration is not finished properly, EG (You have to actively recalibrate in the recalibration cycles last 15 seconds) you will incur heat damage upon the cloak systems from processor overload.
This theoretically would eliminate AFK cloaks and still let people stay cloaked as long as they want or need, while also giving no more excuse for complaining about AFK cloaking and a fair shake of the stick for people wanting to try and whack the clumsy/inattentive cloak ship pilot.
In addition, it would avoid messing with local, avoid the quagmire of the defenders forcing a person out of cloaking and avoid complaining from people saying
((I want my 100% safe, pay to win, physiological warfare, seal clubbing .50 BMG point blank no scope head shot, cloak and scoot with cyno blop! Don’t take it away from me!))
Though it would not stop the complaints of
((I want my 100% safe, set it and forget it, get rid of local so people can’t tell if I get lazy or go AFK so things are easy because I pay to win and want my physiological warfare and easy seal clubbing .50 BMG point blank no scope head shot, cloak and scoot with cyno blop! Don’t take it away from me!))
This too could be implemented for mining to stop AFK mining… Theoretically.
Say after a random number of mining cycles, the mining computer must be re-calibrated to keep mining functions in operation.
For example
Targeted asteroid, engage mining laser, after random number of cycles (we will say 3 this time) a re-calibration alert is sounded, the re-calibration must be done in the last 15 seconds or whole mining cycle and yield is lost and mining laser is disengaged and mining systems go offline for 2 minuets because of mining computer falling out of calibration and will take 2 minuets for re-calibration to compleat before mining operations can resume.
However, should you fail to hit the recalibration cycle in the last 15 seconds of the 2 minuet recalibration, your mining laser/strip miner will suffer heat damage from processor overload and every 15 seconds will incur more heat damage until destroyed.
Preceded by an audible chime to warn of the CPU going critical at the 15 second mark.
Meaning inattentive/AFK miners will get nothing but damaged equipment, lost profits and little to no ore.
To be even more devious, make the over heating CPU chime the same as the ore hold full chime. 
Which theoretically should increase the price of ore and minerals as it would require attention to harvest valuable ore and cause a shift in ore and mineral prices. Maybe a lot, maybe a little. But over all miners would be able to charge more for ore as it would be more difficult to get than just targeting a rock and pushing one button until the rock is gone.
This is just a suggestion, nothing more, nothing less.
I could be wrong and completely off the mark too, ya know. ¯_(ツ)_/¯
