By the time I get to putting them on the Blocked Senders list, will there
be
anyone left ?

Once you've blocked the ones mentioned and those who can't help but engage
them, you'll still have some folks here.

Try it!

I plonked my first three today..so far so good. One of them hits the SEND
button 2-4 times after quoting a whole page and adding his 'One liner' Grrr
