Depending on whether you're registered with personal or corporate email, and how much control you have over the platform in question, you can distinguish the source with fairly high reliability.  Just generate a new 'bob+nanog70 at' style address for every event you register for, every website that requires a contact address, every mailing list, ...

If you're concerned that people will twig, and use the naked '[email protected]' address, you could work with multiple names including a hash that look like internal nonsense, e.g. '[email protected]', or block the un-plussed '[email protected]' entirely and use e.g. '[email protected]' for people you trust to have your real, non-circumstance-specific email address.

I know people who do this, it really depends how much you care about being able to trace and block people who are either scraping or re-selling your details.
