Inevitable, if a little sad.
For those arguing that this will cause Evey some kind of harm, I honestly believe you're overreacting. What's more harmful, continuing to let the (understandable) resentment toward Evey foment, as it has continued to do for a long time, regardless of any (marginal) improvements in her demeanour? Or making a decision which ultimately benefits the majority of the forum's users?
I think maybe there are some feelings of guilt fuelling this reaction, as I've seen some highly 'critical' posts about Evey from people who are now expressing their dismay at her ban.
I'm a firm believer that it's much crueller on the individual concerned (as well as the wider community) if the rules are consistently bent in order to accommodate them - it can often make them feel as if their disruptive behaviour is being validated to an extent (see Farmaz) and thus make them value their 'special' place in the community all the more. When they revert to their old ways (as Evey was consistently observed to do) and the consequent disciplinary action is taken, it has all the more emotional impact.
I'm sure Evey's feeling bad, and that's terrible, but just look at the last few days in Gibberings alone. That tells a far better story than I ever could.
And with that, eff yez all. Ní bheidh mo leithéid arís ann.
