Thanks, to both comments.
Actually, I was thinking of those that had extra characters, street addresses, etc in the BTC address, making them invalid.  I guess the same would apply; the funds got left at BitFunder, unless LR can somehow claim them.  

This was back on p. 58 of this thread:
"Among the BitFunder public keys:
""  - A null key.  This user (Single?, Multiple?) holds several assets.
"14oQSdpw56jv3Xn49EM58nNY5RSDbiPGwr  " - probably valid, but has trailing spaces.
" \tBalance \t 1Dxg9ZazutpaNkS3Yu5NwMsBHuHTRPdkn" - Uhhhhh....
" 155TY9EpfpML46QA5bhYxRkxXpcJJFZfxU" - leading spaces.
"150 Vernon Ave. #400 Vernon, CT. 06066" - Dude.  That's not a bitcoin address.
"https:\/\/blockchain.info\/wallet\/3d0719da-52a1-" - Neither is that.
"e4c966be-7fe4-45fe-a5e1-7781f3081e04" - lolwut?
"13yEHkfHB9Hc7c1JZ15qqSP2Zw8hQugA9k13yEHkfHB9H" - Not a valid address, and a holder of 15 LRM bonds!
"635a91d71c72e64f2be449065407ac59b213eb127b279" - Another LRM holder (2 bonds) who doesn't have a clue.

There are probably more creative entries.  Just found this on a once-through the assetlist...  "
-----------------
On another matter, just for fun, I just counted the different assets (companies) at BF and found that 18 of the 40 have frozen their trades- no trades in the last (at least) 48 hours.  Guess the rest are non-US.
