I commented on this article last night, and it was finally approved at 2am according to my emails - this morning the comments had been turned off. I feel incensed by this. 
If the issue is the workload for the moderators, why not keep the 40-or-so comments that had been approved under the rules, and then stop any further comments? At least that would give people the opportunity to like comments...
The only reason can be to disguise the fact that so many people are up in arms about this.
Has anyone here complained to The Times? I'm sure many general subscribers have. I just wondered what their reply was.
