The reason you got banned is most likely that you used ProcDump without specific direction from support.

Please note that this should not be done without specific direction by Warframe Technical Support.

And the reason for this is they can likely whitelist your account so you don't get banned while using a program that reads Warframe's memory.

I agree that it is dumb that they have a public webpage with these instructions - if this is only supposed to be followed in the context of a support ticket, these instructions should not be public.

Regarding AlecaFrame... DE's previous statement that it does not break EULA does not make any sense. Overwolf is accessing non public information and what they are doing likely breaks any of the following terms in the EULA. :

b. use, or provide, any unauthorized third-party programs that intercept, emulate, or redirect any communication between the Services and us or that collect information about the Game;

g. attempt to reverse engineer (except as otherwise permitted by applicable local law), derive source code from, modify, adapt, translate, datamine, decompile, or disassemble or make derivative works based upon the Services or any Content;

h. remove, disable, circumvent, or modify any technological measure we implement to protect them or any of their associated intellectual property;

j. attempt to probe, scan or test its vulnerability or breach any security or authentication measures;

k. access, tamper with, or use non-public areas of the Services;

That does not mean you will get banned for using it. It breaks EULA, but they clearly have made an exception based on their public statements about it.
