Allow me add my share to this!
I have been in black for a short time and before I did so, I was receiving 7 junk emails in my junk box and about 7 everyday on average in my inbox.
I turned into black, my junk email is now with 3 to the max per day and regularly only 1 junk mail per day! The numbers which goes directly to my inbox has been reduced to 1 or 2 per day!
The one which came directly to my inbox had my address directly copied from sites I visit and most of them now I hide my email addy only on TSF! I guess it was copied since the email were not sent to many clients but only me!
I came back to red and it’s still 1 or 2 junk mail per day and I receive more regular junk mail from sponsors of competitions I’ve participated on this site!
