Thank you @timcliff for responding.

ِAnd Sorry for bothering you with this. I am not a follower of craig-grant, but I thought it was not good for steemit if a user with high rep was forced out like this.

But I have been investigating the matter for some time now. I think I found (like you said) that the downvoter ( @fulltimegeek ) might have had a good reason after all :(.
