I don’t have anything to add to the criticism of this idiot’s approach, but I can offer this piece of advice for online dating in general:
When you are logged into the site,
TURN OFF THE CHAT FEATURE.
Do not accept IMs. Adjust your account settings so that IMs will not happen. Keep poking that setting until it sticks. Just stick to PMs.
Which is not to say that PMs will be free of douchebaggery. They won’t be. But in my experience, nothing good comes from guys who send IMs. Weeding out the impulse-contact set drastically lowers the volume of stupid coming your way.
