Look at these videos that a member of the community recorded:
Fifa 13 UT - Cheaters Brasileiros #1 - YouTube
These players are bugging matches. They use a trainer to take illegal advantage from the game (Ultimate Team). This trainer gives an automatic win to cheaters in an online match against fair players.
This is really annoying, because:
a) It consumes contracts, moral and fitness of our players
b) In some cases, that illegal win count as a lost to the other player, frustrating his efforts in order to win divisions on Seasons, or pass through stages on Cups.
On top of that, you have crazy prices of players on the PC market.
Here is a list of nicknames (on Origin) of some of these cheaters that are shown in the video (most brazilians).

These people are ruining the game, you can not play a single normal game anymore. They are destroying the community. PLEASE, TAKE AN ACTION!
This is already reported in it several important Brazilian community forums. I hope you take the right attitudes. Ban these cheaters.
