I've found the whole thing quite amusing, particularly now with the person being barred from editing further on wikipedia. I was surprised at how light the bullet point list was in your blog though 2B. My first thought was "Is that it?". Still, it's a very unusual and rather comedic thing that's been going on, so definitely worth the interest in my opinion.
To be fair, I only looked at the stats in the table. I'm sure if I looked back at some of edits of the written content, there'd be a pattern too.
Edit: Just had a quick look. These two statements were added by the suspecious accounts:
After two very impressive away games against Mexico and USA, recognised in both New Zealand and USA, former All Whites' captain Ryan Nelson said the team had gone up a level under Hudson and he had "never seen New Zealand teams play this way"
New Zealand emerged as the 2016’s biggest climbers in world football, moving up a whopping 54 places to 93rd on the back of an OFC Nations Cup victory that both qualified the All Whites for the 2017 FIFA Confederations Cup and furthered their FIFA World Cup qualifying ambitions
