I afraid i wont get any answer from support team, via support mail again, since it seems its one side communication and support dont like to answer to mails containing logical arguments, they are rather eager to just answer to silly kids mails with stupid questions.
What is a Ban?
"A ban is a disciplinary action by a Game Master when a player is found to have broken one or more rules laid out in the Community Standards and Terms of Service. It results in a player's account not being able to log on to Spiral Knights. "
Also it says inside ingame ban notification that breaking Terms of Service will result in ban.
Reason of ban: Evading a suspension by using second account.
Now back to Terms Of Service and Conduct Guidelines
http://www.spiralknights.com/tos.xhtml
After reading it twice, there is no point that will even suggest that "Using second account to evade a suspension" will result in a ban.
Or am I blind? Its there but i dont see it? Maybe someone else can point it out? Exact location in Terms Of Service which will even slightly even suggest that using second account to evade suspension is bannable offense?
Or maybe its not in there? What, you are banned for breaking TOS but actually the reason you have been banned fo is not in TOS?
Doesent it mean that you can actually be banned for ANY MADE UP reason, anytime and TOS is actually just nice made wall of text that doesent mean anything?
from http://wiki.spiralknights.com/Ban
"DO NOT:
Use forum posts, in-game mail, or in-game chat to try to appeal your ban. Appeals must be submitted via the above support contact methods so that Three Rings has an official record of them.
Urge others try to appeal your ban on your behalf--Three Rings can only discuss account information with the owner of an account, for privacy reasons.
Create a new account in order to ask about a ban--this is called ban evasion, and is in itself a bannable offense."
Oh, and to answer your question: "Doesn't it mean that you can actually be banned for ANY MADE UP reason...?"
The technical answer is yes, and it's in the TOS:
21. General Provisions
You may not sublicense, rent, sell, assign or otherwise transfer the rights or obligations granted to you in this agreement, and any such attempted transfer shall be void. If any provision of this agreement is held to be unenforceable for any reason, such provision shall be reformed only to the extent necessary to make it enforceable, and such decision shall not affect the enforceability of: (i) such provision under other circumstances, or (ii) the remaining provisions hereof under all circumstances. Three Rings' failure to enforce at any time any provision of this agreement shall in no way be construed to be a present or future waiver of such provision, nor in any way affect the right of any party to enforce each and every such provision thereafter. The express waiver by Three Rings of any provision, condition or requirement of this agreement shall not constitute a waiver of any future obligation to comply with such provision, condition or requirement.
Basically, Three Rings can effect a proviso to modify any part of their TOS to make it enforceable. That means bending any part of their terms to fit an enforcement.
Most gaming companies have a similar "we can do anything if we want" clause in their TOS. Go read a few from various F2P companies, you'll see it there too. But I mean, it's right there in the wiki, so.
