[anonymous]

If I am not mistaken, I personally maintain at least 3 distinct identities on the net. I think I might have more than that, one-off accounts made with a one-off email for some site that I've forgotten. And I make VERY certain to never ever mention anything about one identity on a communication channel used by the other identities. One of those I only ever use through private browsing mode to avoid leaking cookies to sites that track these things. Relatedly I suspect some of the people I know online are one and the same physical person, but since I know them through different channels, I cannot actually ask if this is the case, plus it would be extremely rude to do so.

I hope somebody some day comes up with a better way to keep threads of identity separate, so you don't face the situation where you're denied work or university because you woke up in a bad mood one day and said something angry about someone online to a friend of yours.
