StackExchange ToS section 3 currently reads
Stack Exchange reserves the right to remove any Subscriber Content from the Network, re-post to the Network any Subscriber Content removed by any Subscriber or former Subscriber, suspend or terminate Subscriber’s right to use the Services at any time, or pursue any other remedy or relief available to Stack Exchange and/or the Network under equity or law, for any reason (including, but not limited to, upon receipt of claims or allegations from third parties or authorities relating to such Subscriber Content or if Stack Exchange is concerned that Subscriber may have breached the immediately preceding sentence), or for no reason at all.
Well, this is in section 3 and immediately follows the wording that says
Subscriber represents, warrants and agrees that it will not contribute any Subscriber Content [that infringes copyright, is harmful, etc, hereinafter I'll be calling it "bad content"]
and so I guess the intention was that all these reaction measures listed are only to be used in cases when the Subscriber publishes "bad content". Yet with current wording all those reaction measures are not in any way linked to publishing "bad content" and there's even this no reason at all phrasing, so it looks like it can be interpreted as "StackExchange can delete anything or ban anyone just for lulz (including banning the OP for posting this question)".
I guess this wording should be revised.
