Easy enough to empirically test (and would be interesting to know):
1. Steal underpants, 2. ?, 3. Profit
Wait, sorry. Wrong plan.
* Set up a dummy mail account on a gibberish domain or subdomain; the
account name and domain should be something random enough that it's
not likely to get hit by a 'try this dictionary list @ example.com'
scheme (i.e. embed some numerals in strange places, 't1es1t')
* Sign said account up to the ale list, and post.
* See how long it takes to receive spam at that address.
* Repeat with a different address but post only to a list which tries
to obfuscate whatever public archive.
Be interesting to find out if both get harvested, only the
unobfuscated one gets harvested, or neither; as well as finding out
what the "time to be spammed" is.
