Pokemon GO

So few weeks ago after one update where people claimed that their accounts were lost and had to start over due to a certain update I found out that someone is using my username on the game.
I tried making a new account and typed Jei-Dinofelini as my name and it said that it is not available. It made me rather mad about this. Why would someone take MY username on the game?
So warning.
Is anyone sees Jei-Dinofelini in the games either on the Pokestops or Gyms. This is NOT me.
I have a different username. 
I tried making this account few weeks back as I thought that my account was lost but it wasn't.  The issue was that after that certain update the game just logged you out and you just had to log in again. That's all.

The new update which was recently released is awesome.
You can set any Pokemon as your walking buddy and earn the candy to evolve them.
I am finally able to evolve the rare Pokemon which I cannot catch or find....

I find kind of weird....
With the rarity of certain Pokemon. 
They say that Dratini is rare yet I see more than one spawn near my house and once it was in my house lol.  
Eevee or growlithe or whatever they are I think uncommon or common I don't remember. They are literally extinct here..   I go for miles and days and hardly ever see any of them in my sightings.... it's kind of frustrating...
So this feature has given me some hope now. If I turn on the game everyone I go out I will earn some required candy for evolution. I am in the process of walking Vulpix. I saw it only once and was lucky enough to find and catch it... 

I really like Ninetales.  It was always one of my favourite since childhood. I really want to get it. Screw the Dragonite. I can catch enough Dratini in my area. No need to walk them. XD

So umm...
Who else plays the game?
Here in UK people are obsessed with it lol
