Too bad you couldn't use a block of addresses in this case. Unfortunately, you would have to use a block size of 32. You can't use a block of 16 because a single block doesn't include all 15 of the hosts you want to deny (0-15, 16-31, 32-47, 48-63, etc.). If you could have used a block of 16, you would still be denying an additional host that you didn't want denied (providing all 15 of the hosts you wanted to deny fell in the same block). It's even worse with block size of 32 (0-31, 32-63, 64-95, etc.)
access-list 50 deny 10.10.10.32 0.0.0.31 The problem here is that you're also denying hosts 32-34 and hosts 50-63 which makes this useless unless you don't care about the other hosts!
