You got flagged for the steady cashouts you talked about in your first sentence.
This article covers more.

Unfortunately you will never be able to use WU to deposit or withdraw from any poker site ever again. According to the article you can pass an 'interview' to reinstate but good luck.
Ironically if you actually have WU enabled you should never go to different locations as that is flagged in their system. Therefore you should 'relevel' and go to the same location everytime to prevent a ban according to the article.
One way to take this is as a compliment. Bovada enables WU betting on the fact that you are likely a net depositor (i.e. loser) and you have shown that's not the case. Think about it... this thread is about money and all the winning players get checks and wires. If winning players could use WU you would just see non-stop vomitous REQ/REC WU posts in this thread but that is not the case. Seriously I've been lurking this thread for a while and have not seen any posters w/d a large amount of money from WU like 30 or 100k or something..
So the good news is that you need TWO good big national banks. You will be on checks and wires like the rest of us. Remember that checks will come every week. As long as you have a backlog the 10 business day rule is halved. Same goes for wires.
Also, been doing some research on international check clearance time frames and there has been a lot of legislation on this. Basically 90% of international checks must bounce SIX business days after deposit and 99% will bounce ELEVEN business days after deposit. SO your check has a 1% chance of bouncing after 11 business days has elapsed.
There's a limit to this stuff guys and banks have to follow laws too. They can not just willy nilly bounce a check from september for example...
