You can add bitcoin adresses to all sorts of directories, but they're really just useless (See Ninja's reply.).

You have https://www.scambitcoin.com & https://bitcoinwhoswho.com/scams that i know of.

These directories would only become somewhat interesting if Electrum somehow adds a plugin with a blacklist of these addresses, but considering the amount of false positives & the way malware would be able to simply maneuver around such a block & the fact that scammers can generate endless new addresses just makes it utterly useless to do. Not to mention that it's really a step in the wrong direction, towards centralization et al.

TLDR; be your own bank.
