Emergency: Please check Wikipedia:Administrators' noticeboard/3RR History 

I was initially perplexed (flummoxed is more the word) by the strong accusations in your explanation for the block. However, I now realize what has happened.

To see my initial complaints (there were four), you will now need to go to the Wikipedia:Administrators' noticeboard/3RR history entry (see link). You will notice that it probably reads a little differently than the one you read.
The eventual decision can be found later in the page history (see link). 
You are not going crazy (I thought I was when I checked the current page). You will notice on the history page that  considerably altered the page. (see history page)

I'm still not sure if I believe my eyes. Let me know if I have this wrong, but it seems that   has altered history. 

I don't blame you for your strong reaction. You assumed good faith on 's part. No hard feelings. It's hard to imagine or anticipate that kind of audacity (although it doesn't really surprise me). Be it said that a good deal of editors on the Canada page who had given up because of  and  will be relieved at these self destructive developments.  

I'm going to let an administrator handle this. I will indeed limit my dealings with G2 from here on in. I wish G2 well, and hoped he/she had fun while it lasted.
