forget about those lists - it happened several times already that those liste were sold to spammers (for big money - because THESE adresses were verificated!).
what else:
1. use another than your personal addy in forums and do not use @, use capitals AT (ok, banal)
2. make a (new) address at gmx.net. This Germany based company has excellent spam-filters (90 - 99% effective in my experience) and it's free !
There might be other providers with good filters in UK or USA; but afaik gmx is best.
3. spend about 1 £ / 3$ per month for "Spam arrest" (they have a 30-days free trial period too - see
http://spamarrest.com).
QUOTE (from that website):
"When email arrives from unknown senders, a reply "CHALLENGE" email is sent back asking senders to verify themselves by clicking on a link to the Spam Arrest website.
The link takes the senders to a page where they are instructed to type in a word that is shown in a picture -- the "RESPONSE".
It is easy for a human to answer the "CHALLENGE", but automated systems, such as those used to send spam, are stymied and cannot authorize themselves. "

OK, this looks like advertising, but it's here as info. I know a guy who runs a web publisher company - and he has got rid of spam with this product.
