thanks for the questions. 1. DeleteMe's been focused on the biggest and most cumbersome to remove sites. We pride ourselves on doing a thorough job and we use real people to make sure searches are comprehensive and removals complete. we're careful about the quality as we add new data brokers. that said, we should - and are adding more and more. our experts also help with custom requests. what we call "repopulation of data" is also a systemic hard-to-control problem. this is why DeleteMe's a subscription service that keeps checking and removing for a single price all year.
2. best practices are things most HN concerned people are doing... pass manager, tracker blocker, not everything in a single cloud, vpn, etc. the most interesting thing our Blur product does is let you "compartmentalize" key credentials for each 3rd party you exchange data with. meaning: Blur gives you unique emails, phone, and credit cards as well as passwords, stores them locally, and has a proxy server to route between your private credentials, and the new ones you generate. you can use gmail as your "private mail"
lastly, i'd stress: these things help a bunch to make it harder to correlate your identity cross-domain. that said, anonymity is - and has long been - very difficult to attain and expensive to maintain. don't kid yourself on the difference :)
