I dunno, maybe your GM is more harsh on you than I am on my players. I'd just make my players roll for hot-sim addiction rather than trying to hose their brains for doing data searches
'Oi! Player interpretation there, not fueled by actual game experience. Careful Top Dog, you give me a bad name.
More "Evil GM interpretation". It's what I'd do if someone blatantly uses hot sim all the time as a (relative) computer nublet. Well probably something milder first, just to let them know it's dangerous.
Not saying you can never use hot sim, mind you - but it comes with danger, and using it to search for run-specific things can end up badly if someone's paying attention. Of course not every innocent search will end with someone frying your brain, but hey, one search on the wrong topic in the wrong place can be enough.
Well, yeah, this
is shadowrun after all :-) Its like sending your face into a mafia bar to dig out dirt on the big boss man. someone would notice and beat shit out of you.
thankfully, with a dicepool of 8, you just can't search for anything restricted or hidden, its just not possible with that dicepool.
It'll find you basic stuff though; articles, blogs, social media pages etc. probably nothing that's gonna get you killed but stuff that may be useful in the long run.
Hot-sim's main danger to the basic user is that it is addictive. that is something that I would be enforcing
