If you are one of those concerned about knowing who has blocked you on in your FriendFeed Network then ffblockr is what you are looking for. No I am not marketing this stuff for any benefits in return but I know people who would spend hours worrying who blocked them. All that the service needs is your login information with a promise of never storing it along with an email where it can send you the report. Plus it also displays your name on the homepage if you are on the top 5 of the block list, talk about getting publicity.
