Wow, apparently they had a stock line they used when customers paid them money to try and view those messages that were sent by fake accounts, got a message saying the account was unavailable instead (because it had been deleted for being fraudulent), and complained to Match.com that they thought they'd been swindled:

"Please be assured, Match.com does not send members misleading notifications, e-mails or winks professing romantic interest. We have too much respect for our members to ever compromise their trust. If you have received communications from members with profiles that are not immediately available, the member may have temporarily hidden their profile."

That is impressively scummy.
