I’m 99% sure they are still using an MITM to get the colors for the exo posts like this one:
The map client I used to have read game memory:
The shop scanner (before the in-game knowledge-base tabs) I made actually read the items on the stand from memory by walking near it (aka read all blocks from memory, which is why I didn’t make it open source because I didn’t want the block reader abused):
Generally I post what I do on the forum here so they know and they can tell me to stop if they have a problem with it, but they’ve never publicly stated that it’s okay to MITM or read memory. (they have told me in DMs that they will tell me to stop if there’s a problem).
