How do you tell people you are not interested?

According to the Harlequin Romance Report 2008, 32 percent of men and 43 percent of woman have given out a fake phone number to someone they are not interested in. This is an easier way out for people than telling the truth.

I figured a twist to this would make an interesting new poll. So how do stop communicating with someone on a dating site? Do you give them the cold shoulder and just stop emailing them or do you tell a white lie to make them feel better and make it easier for you? Lets see if the results are similar, place your vote now.
