Well done, Ipquarx. Well done indeed.
The hack is impossible to detect on the server. The client is a different story but just remember we have control of it so there is really nothing you can do.
Ahh it reminds me of VAC
...up to a point.
There are ways of telling when someone is using the floathack at least. It's not always obvious but if it works like I hear it works (disabling movement packets alone) then it would probably be obvious because the server would be receiving everything else.
I remember the way you talked on Furling's server, and frankly, I'm not sure if I quite trust you 100%, but I have no reason to doubt Ipquarx. You did say it would be "great, er, terrible" if someone were to tamper with the site Blockland receives its updates from, and all around struck me as a bit worse than ddc, although some of that may have been just posing or playing around (I am unable to take much in the way of jokes on the internet).
...Didn't you once host an RPG? I swear you used to host an RPG.
Anyways, back to the point, Ipquarx, 10/10 undercover agent. I looked over those files, and holy stuff are they incriminating.
I just hope there's no secret download links within that will allow people to find BLhack.
