The reason they suspect cheats is because Hyperfocus is a cheater’s dream perk. Are they just cracked at hitting increasingly difficult skill checks, or are they just using a script that automatically hits great skill checks for them? It’s especially suspicious when it’s run outside of the typical gen jockey build with Stakeout etc.

Depends on what item and what you mean by "counter", I think. There isn't anything that just depletes item charges in the game anymore to my recollection, but that doesn't mean you don't have answers overall.

Lightborn hard counters flashlights, for example, but you do tend not to find such hard counters for the others. Shadowborn, Forever Entwined, Fire Up, and Two Can Play also exist to weaken flashlight use, to mixed effect.

Toolboxes, I kinda got nothing for you, if it's stacked repair toolboxes used at the start of the match there just isn't any countering it. If it's sabotage toolboxes, though, you can get some good value out of Agitation and Mad Grit, so that's something. They also do well enough with stuff like Starstruck and Forced Penance, so mix and match if you're worried about sabotaging.
For repairing… idk, Corrupt Intervention? Repair toolboxes are a problem and weren't even countered by old Franklin's, lol.

For medkits, I've always felt No Quarter was meant to be a medkit counter, but its effectiveness is a little unreliable in my experience. Still, it's there.
Broadly, because medkits aren't that fast anymore, you can reliably weaken medkits by just applying Mangled or some other healing slowdown. Medkits are also the best case scenario for Franklin's Demise, as the time taken running back to their item adds on to the amount of time it takes for them to heal. If it's post-unhook Resurgence combos you're worried about, bring Gift of Pain (Weeping Wounds, if you don't own Pinhead), as it counters that perk in general.

I would broadly assume you aren't worried about keys, maps, or fog vials, but if you are… Overwhelming Presence is still pretty good there, it's a nice chase tool. Broadly you just outplay survivors with those items normally, though.

Those are some broad tips at least, I can probably be more specific if you want.

Anti-cheat.

It's been getting out of hand for years now. Still waiting on DBD to open the Stockholm server so that Frankfurt can finally catch a break.

in regards to content creators I think they are put in a special que without hackers or at least with less (I remember that being a thing mentioned a few years ago at least for the big ones)

Edit for downvoters, this is what I was referring to from from 3 years ago:
