Ironic thing is that the insane UI lag is caused by server authentication of every UI action, which was done specifically to stop RMTs. So SE makes the players suffer with a horrid UI in an attempt to stop RMTs, but they won't actually stop RMTs when they are reported.
I can see how that can help prevent hacking, but it really does nothing against botting. Its just retarted to make everyone suffer with a crappy slow UI, to prevent hacking, when if they just had a Special Task Force that actually knew how to monitor sh*t then hacking would be caught anyway.
Most real botting programs work by intercepting the data being sent from the server to the client. The botting program is then responsible for running player designed scripts and sending commands back to the server, thus cutting the UI out of the equation completely. Using bot programs like this allow for much more sophisticated bots to be created.
Server UI authentication is in place to make sure that every command coming from the client was done so via the UI. There is likely some signature tacked on to every message sent by the UI, and the server will not process any command without the correct signature. This signature is unique for every command sent by the UI, and the server is responsible for decoding and validating each and every one of them, thus causing all the UI lag. It could also be encoded with something like DES (data encryption standard), which would be impossible for botters to crack.
Either way, the authentication has to make the round trip from client to server to client, and that round trip takes up to half a second depending on your connection latency. So the fastest you will ever be able to open your inventory will be the time it takes for that message to make the round trip, plus whatever time it takes for the server to process the authentication, plus whatever time it takes your PC to render the menu.
These bots you see currently are probably being run with keyboard macros. There are several of these programs available for free online. They probably work by just spamming the TAB and 1 keys over and over to target and nuke anything that walks by. Since the UI is still being used it completely circumvents the UI authentication.
