Sorry for being childish back there ;-;, anyhow by playing mabinogi you agree to this:
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.
All from their ToS, of curse there are other laws that are over this ToS but you are forced to provide solid proof that for example Nexon (company) and or employee stole your credit card, your Hd pron, or we. Long process, nothing can really be proven on internet (unless is pedo stoof or serious bissniss), etc. Trying to sue on of these companys is like trying to God because you got brown eyes instead of blue.
