No it isn't - not if the same person sends you a mixture of useless and usefule emails. And it doesn't solve the problem of your email adress being made public.

With FB, you simply go on it when you feel like / have the time.

Yeah, actually, I do that all the time. Regex's are awesome, and so is spamassasin. There are plenty of other "rule-based" type tools out there too.

What is the problem with an email being public? I don't think I understand what you mean.

[gotofritz]

Yes, of course, we all have the time for endless fiddling with regular expressions... please

I never said you had to. I provided a list of tools. You have yet to bring anything worthwhile to the discussion except to complain about tools you don't understand.
