Yes, I have had problems with that site for a while now. I have pretty much given up on using the site. You're right using the word worthless. Between the problems with Rentboy, americanmale.net charging (mancheck plus site) to get access to the boys email addresses and phone numbers, and the outdated/inactive ads (literally hundreds with no contact info) on m4rn, the ability to search and contact has been reduced. I pretty much only use this site now when looking or someone to hire.
Frustrating to say the least.
