I was playing in a tournament and these two were clearly dumping chips to each other.

One of the first hands they sat down Claudia puts 90% of their chips in pre flop only to fold to papatodas007. IT was a rebuy so Claudia would commit a bunch of his or her chips to the pot and then just fold to papatodas. IT was blatant chip dumping. They would get in almost every hand together and isolate to a heads up spot. THen Claudia would commit a bunch of their chips and fold to papatodas every single time. Who puts in half their stack or more like 7 times only to fold to the same person repeatedly?

THere any gumshoes here that want to look into this? I have no clue how to, but something has to be done. THey weren't even trying to be smooth about it. It was just blatant dumping. It was so obviously the same person just on two accounts.

Sending to security.

I think that they have one other name to..its papatudo111 I have been at the same table in a mtt with papatudo111 and papatodas007 and both are from Brazil.

I believe the OP. I have seen claudiacardoso many times make a very odd play/bet and with the same person on the table, like call their big raise with J/7 os and immediately rebuy and repeat. I initially thought it was some sort of Battle of the Donks, but the OP makes a lot of sense.
