Can TD Block Players?

If I create a turn-based, multi-day, online tournament, as the TD do I have discretion to block/refuse any player's registration prior to the beginning of the tournament?

To be clear, you are saying that a TD is able to block a player from participating in their tournament before it begins?

Thanks for responding.  So apparently blocking is possible.  I know that it is possible to block players from sending me messages or posting in my blogs using the privacy settings in my profile.  But I don't want to use this method for blocking entry to my tournaments.  

I would prefer instead to be able to evaluate and vet players once they register for my tournament and make a decision at that time as to whether I want to allow them to play in the tournament.  In other words, to make the decision to admit them or not after they have submitted a registration request to join the tournament.  Is this possible?

He is not wanting to block a user, just vet players in his events.

I thought a TD can can remove players but I'm not 100% sure,  as I've never run one here. 

It's not those that I have previously vetted and blocked (say using my privacy settings) that I am concerned about.  It's those who register for my tournament and whom I have no prior knowledge of, and have not previously vetted or blocked.  I want to be able to check the players as they register, to see for instance if they have a history of withdrawing from tournaments, timing out of their games - that sort of thing.  I want to vet them as they register and admit only players that I feel are likely to complete the tournament, not delay the tournament, etc...

The best way is probably to hold invite only tourneys that way you have more control.

hmm interesting..
