> unique alias for each account (e.g. github@myname.com, reddit@myname.com, etc.) in order to mitigate spam Never done this and barely get any spam or had any problems opting-out of stuff later. Wouldn't legit companies like GitHub and Reddit get in big trouble for sending spam you can't opt-out on so this isn't really something to worry about? Sounds like you'd be far more at risk having your main email displayed publicly online which is almost impossible to avoid in the long run and I don't hear of people getting swamped with spam in these cases.
