lol no TOS would allow a company to scan your computer. An installer could scan its integrity, in the case of MMO do integrity scans on itself any time you login would be legal. What that means it could scan the .dll for example find that does not match what should be and take action. Scanning the entire Mabinogi folder would not only be unnecessary, but would be a illegal. Silly as it may be for example someone might have personal data in that directory. There is no way for a company to insure that a folder is used explicitly for their own software.
So idk where you get the idea the new TOS would allow Nexon to go into your computer and look at anything. Not even a system admin has those rights and I know used to be a system admin.
Anyway this what their actual TOS says
2.4 Hardware and Software Access. You hereby acknowledge that:
2.4.1 The Company has the right to obtain, without notification to you, certain information about your computer or software, including, but not limited to, your operating system, identification of your hard drives, central processing unit, IP address, and Internet browser for purposes of identification.
2.4.2 The Company has the right to obtain, without notification to you, non-personal information from your connection to the Service or Site for demographic purposes.
2.4.3 The Company has the right to obtain, without notification to you, information from your computer, software, and parts or portions thereof, including, without limitation, your computer's random access memory, video card, central processing unit, hard drive(s) and any other storage devices to assist our efforts in policing users who may develop and/or use "hacks" and/or "cheats" to gain advantage over other users. The information obtained in this Section will only be used for the purpose of identifying persons or entities not in compliance or believed by the Company to not be in compliance with this Agreement and any and all other Company rules, policies, notices and/or agreements.
The problem, this is all boilerplate, so this what Nexon really means.
-Translation
2.4.1
Nexon can compile date on your system hardware to make a hardware ID... very useful in banning someone with dynamic IP's which, is like everyone in the united states.
2.4.2
kinda explains its self, all it means is we look at everyones IP make fancy chart and look at where our market is.
2.4.3
We have the right to scan our own software in either passive or active memory on any storage medium. In addition any software that hooks into our software in violation of section 2.2 .
