yes. just report the 2 names that you suspect of collusion and they take every matter very seriously. here is an example of a report i got back from them.

First thank you for taking time to report your concerns. We take the
integrity of our games seriously and appreciate vigilant players who help
us monitor the games. I have completed my review of the accounts 'gph08'
and 'Druidsorcr'.

The first thing we check is the relationship, if any, between the two
players. In this case, I do not think they know each other. They are from
different states, and have none of the common indicators lit. These
include things like shared computers, transfers to and from each other, and
so on. Of course, this doesn't mean that they are not friends, but it's
certainly a good sign.

Here at PokerStars we are able to replay hands with all cards face up. To
review this case I retrieved all hands played by these players to date.
There was none; Today is the first time that they have ever played
together.

When checking for collusion we simply replay the tournament with the cards
face up. We look for several things which include, but are not limited to:

1. Squeeze play - the players reraise each other in an effort to drive a
third from the pot.

2. Pot building - the players put in small bets that entice others to
call when one of them makes a big hand, in the hope of building a larger
pot, and perhaps commit a player.

3. Stack balancing - the player with the larger stack purposely loses to
the smaller stack to ensure both players remain in the game.

4. Softplay - this is where one player who holds a really strong hand
decides not to bet his hand against another. It is very similar to (3)
stack balancing, and many stack balances are also softplays. Also note
that Softplay is the mildest form of cheating because lots of players just
do not realise that such play is prohibited.

(1) and (2) above usually requires the sharing of hole card information
externally to the game, however for (3) and (4), if two players just happen
to have a policy of not clashing against one another, then they do not
necessarily need to have any knowledge of one another's cards.

I have reviewed the tournament in question, looking for any unusually
played hands by these two players apart from the hand that you reported -
which I cannot describe as anything other than "bad play". I am happy to
say I did not see any strange play by either player at any time; at all
times they appeared to play their hands in their own individual best
interests. I saw no strong hands being folded, no unusual raises designed
to pass chips to each other, and generally no play that was not easily
explained as standard poker. I did see several hands where the players
clashed with disadvantageous results if they were working as a team - one
such hand is attached below where 'gph08' severely cripples 'Druidsorcr' in
a hand which he could easily have folded if they were working together.

Overall, there appears to be no indication that these players are colluding
in any way. Please however do not ever hesitate to report any concerns you
might have about unusual play to us for review. As you can see, we treat
all such complaints seriously, and will do a full investigation into any
such email.
