Also - take into account hyphotetical situation:
1. Someone registered [yourname][1..56]@gmail.com.
2. You registered [yourname]
[email protected].
3. Quite likely that some mischievous person who has [yourname][1..56]@gmail.com now tries to carry on a usual and attempts to register the 57th email... SNAP - hijack attempt
IMO - dont click on shit, keep your shit up to date and stay away from dictatorships. IF someone WANTS to hack YOU - you are SOL, if not - you should be ok.
