Match.com's "clean" standards, focus is singles wanting relationships only
With more than 50,000 profiles submitted to Match.com each week, a team of almost 300 people makes sure to reject the ones that don't fit Match.com's arbitrary but focused standards on what can and cannot be included in them (although Match is planning a separate R rated site soon) according to this Wall Street Journal story (subscription required):
Match.com has its list of banned words -- all the predictable obscenities. But it also has a second, much longer list; words that, when used in profiles, require extra-careful review.
Some of these are surprising, such as "discreet." It's on the list because it's often code for "married and looking to fool around." Match.com is for singles only.
