Take the XY coordinates of the players every single second, then calculate the average velocity compared to what a normal player can run on stims + 15%. Then calculate the max Terminal velocity of a player falling from say, the dam, and match that against the Z speed of the player.
Then check that player median against the expected speed until you see some numbers that are far too high. Then ban them if they repeat offend multiple times a game to raise their median speed, discounting server lagspikes (if possible). If they can't speedhack at the speed of sound then sh*t son, they can't loot that easily.
Speedhacking should honestly not even exist. This is a really easy to code anticheat, and very basic to boot. Should be able to run alongside whatever else is in place.
And for players being able to loot living players, just make sure there is a system in place that item data is encrypted and that a check if the player is actually dead is in place.
And for aimbotters, Please check if the angular velocity is humanly possible per tick, as the fastest reaction time is only ~90ms. Maybe even cap angular velocity to a humanly possible speed, because as fast as throwing your mouse across the mousepad is, an aimbot is infinitely faster. For example if someone has a timespan to break line of sight the first time out of auditory range and kills the other person instantly, multiple times per game, that person should be flagged for manual review or automatic ban.
A similar system may also be implemented to stem against triggerbots.
Or if someone consistently gets quadra kills or triple kills in less than a few ticks. Every game. These are blatant hackers.
These are all very simple suggestions for an anticheat, and they should stem the tide of these very popularly described cheaters.
If someone spinbots (I have yet to see that one), this can effectively nullify it.
Therefore the only hacks left here would be bezier curve aimbots/wallers and such, but if the game can be coded see if mouse aim consistently matches a bezier, then these can be fair grounds for a ban.
And finally if a hacker is detected and banned, please add back the loot of every player killed by them during the raid. Its infuriating to waste hundreds of thousands on labs just to get wiped by an aimbotter that one taps 4 of your buddies in less than 2 ticks. Then for Prapor to say that no, insurance doesn't actually exist on labs.
It would also be wise to contact Chinese Authorities, ebay, and marketplaces like taobao with a request for legal reinforcement and cease and desists, much like Microsoft abuses to prevent low price windows 10 key sales. Perhaps getting a deal with a publisher in China would be the best interest for everyone at this point, so as to stem the in game currency sales.
Probably also have a limit on how many rubles can be traded in raid at once, aka limit rubles brought into a raid by say, 100k, so IRL traders will have much harder times trying to give people their bought rubles.
Also, the flea market should have a check for how fast someone can click, to stop sniper bots and mass manipulation of the market. And its also best to remove trader item limits so as to allow players to actually buy things at a non monopolized price.
There's seriously not that much need for enforcing find in raid so much if the above problems were stemmed to a noticeable degree.
Hope this helps, godspeed Nikita!
