FORBES - Mar 11 - The Internet offer a veil of anonymity that makes it easier to talk before you think. Dating sites are taking some steps to make online dating a much safer and harassment-free experience. Yesterday at SXSW, Elissa Shevinsky, a former dating entrepreneur who helped build OKCupid’s spam filters, shared some developments she was working on. OkCupid had a spam filter that would filter messages with bad grammar or naughty words. OKCupid now has a pilot program that deletes messages with short words. Many entrepreneurs have experimented with making users pay for every message or capping the number of free messages they can send at one time. The goal is to prevent daters from spamming thousands of people with the same message.
