Currently it is undeleted, but I wonder:
Why was it deleted in the first place?
The account which was used to post that answer was created by a person who was suspended for repeated misbehavior. The new account was created in order to avoid the suspension. The answer should not have been posted in the first place. I have deleted it again, because we must not enable suspension evasion. When you repeatedly violate the rules of this community, you lose the privilege to participate in it. A suspension means a complete suspension of all participation in the community, including constructive one (and this particular contribution wasn't even unanimously considered constructive, as indicated by the 6 downvotes). If we show any leniency towards suspension evasion we lose the only tool we have to keep repeated rule violators off the site.
