Ban LabyMod

So a while back there was a thread on the Hypixel forums that pointed out something about LabyMod:
https://hypixel.net/threads/labys-mod-is-now-a-blacklisted-mod-security-advisory.515247/
(not advertising pls no ban)
and I did a bit of research on minekits and on a private testing server where I test skid clients and the like...
and I've come up with some pretty creepy stuff.
I've been able to confirm that the LabyMod hitting animation actually has massive effects - PvP techniques like the "wallbang" (tapping w-a-s-d-a-d-s-w-w and hitting someone who is in a corner) have HUGE boosts in range. Now, this is not only a client-side thing. On SOME servers (including my testing server), it adds up to 0.3-0-4 blocks of reach OCCASIONALLY when using range-increasing techniques like any 8-block technique (basically resetting your sprint every time you get a hit).
I've also figured out that certain file types can indeed be transferred - these tend to be .bat files, unfortunately I've not really been able to find out if anti-virus software reacts to a file transfer within an application.
Due to these findings I'd like to appeal that Brawl codes a checksum analyzer - this analyzes a player's client's checksum and attempts to match it to an allowed/blacklisted checksum, and adds the LabyMod to this (this would also crack down on ghostclients, so I see no reason not to add this).
NOTE: I know people like this mod, but I agree with the Hypixel staff in their view that it's pretty close to a hack client.

 

The thing is, there are a few servers that basically check if your Minecraft ID is modded or not, and then check that ID against a list of pre-checked versions. So if I were to use a LabyMos client which had an ID of 12345, the checksum analyzer would match that up and ban me.
@Ekali I think it would be fine - Hypixels anticheat is certainly better than Badlion's.

 

I'm reasonably sure this can be done.
If you've ever used say a Forge version of Minecraft, if it crashes, you get a notification from the launcher: "It looks like your game is modified" or something like that. This means there must be a version ID check somewhere - I believe it's in the Java code somewhere, I might be wrong.

 

My forums are wayyy to laggy and slow right now to be able to answer this properly, I'll answer when I've got this back on track

 

My main point, that it provides reach/an advantage of sorts, only appears occasionally. I think I have a decent clip of it somewhere,unfortunately my internet connection has decided to start a fight this afternoon, so I'll have to upload it at a later date. However, I'm honestly more concerned by the file transfer thing, which is why I've already stopped using it.

 

Is there not a way to stop people from illicitly transferring files to another player?

Hang on a moment. If I were to crash with any version, my launcher will tell me if I can send in a bug report or not. So why would this be the case? Is it really Forge that sends this info?

 

You probably don't notice the difference in a server.
