Ok I know a website can be blacklisted from google.... is one of the ways this happens is if the website was in spam email? Also I seen this site for a mass emailer with a "safe opt-in" list of people.... now if this is a hoax and I send emails from my computer.... will my computer be blacklisted from sending email or will my email be black listed.... can I get in trouble with my isp? I'm just a little worried that this list might not be safe.
Yes you may get into serious trouble. It really comes down to your countries laws concerning the matter. If an IP is blacklisted, its useless as ISPs and datacenters will most certainly add it to the block hosts. Best way to advertise is word of mouth and references. Mass email/spam campagins are retarded and more so annoying... good luck in your endeavours
