I'm getting upset, hack and please fix my name.

Hi all, I'm BlazinsZ, i have two complaints today, the first one is pretty obvious, my username  has been completely destroyed by the magic of this forum, i just logged (my name was normal) and when i put a reply, became this number, is annoying, ok? , well, if someone is kind enough to explain how i can put my name back, because i searched in my profile and i didn't find the place to change my forum name...i'll appreciate that. I thought about creating a new account, but this user is linked to my personal email, and it really bothers me to create another email just for this.

Second thing, i have a hacker in my league, first time in this! LOL! I'm so new at this, I'm so excited, really, it's so fun to have a hacker in your contest lol (sarcasm).

Has suddenly appeared, with many points, and it is now the first one (in the pic is the second one) , the contest ends in 6 hours. 

I just realized that there is no way to report it, so, Is this a mockery? How do I report it? I've been innocent, I've been thinking there was a button to report, but there isn't! , you tap in the city, and you can see the level, his club, the level disaster, you can't visit their cities, and that's all. If you are a regular player, you know that you can change the name of your city at any time, and also you can change your club. Club, and the name of the city aren't form to address a player. 

Now that we know this, i ask again, how i can report him? If you took a screenshot, 2 minutes later he change his name, and isn't that guy anymore, also, probably he had another name, and poor innocent guys are reporting a player with a random name who doesn't exist now, because we all can change our name. 

Another player in our contest changed his name to try to say to all of us (we already know btw, all in the contest) that one guy is hacking. I'm trying to help, but i don't have any idea how to report this guy, when name, club, and others things aren't form to addres a player, if there is a ''Player ID'' about each player, how i can get that player ID? to make a succesful report, because i don't want to report a wrong player, i want to report the right one.

So is funny how we can send a email reporting a player, and how EA take care about that? i mean, it doesn't make any sense, i don't want to report just pulling a name of a city in a screenshot  knowing that isn't a form to really tag a player.

Last thing, this user hacks the last day of the contest, will he get away with it? will be victorious, right? even if he get banned tomorrow, next week, depending how fast EA take action, we already lost the reward of this contest, the first place. How can I know if the following week will not appear again on the last day?

I'm looking forward to reading an answer that calms my discomfort
