My rooms sets mode (+mD)

Someone join myroom after 10 seconds will received a messages from MyBot in PM is:

ATTENTION: You just tried to join %dmchan $+ . Since we're being attacked by bots, please type: %hucheck. [ $+ [ %nick ] ] <== (captcha) to prove that you're a human. If you do, you will be permitted to join. If you mess up, nothing will happen.

When someone type exactly captcha in PM of MyBot, then get voiced in myroom and received this message from MyBot in PM:

Welcome to %dmchan $+ , $nick $+ . Sorry for the inconvienence you experienced!

But it NOT work, and have some errors are:

1. Someone receive message in PM but when they type exactly captcha in PM of MyBot and NOTHING happened.
2. I see this line after fews seconds repeats many time and never stop:  Scanning Hidden User: <nothing here>
3. Nickname received every 60 seconds this repeat line in PM:  ATTENTION: You just tried to join %dmchan $+ . Since we're being attacked by bots, please type: %hucheck. [ $+ [ %nick ] ] <== (captcha) to prove that you're a human. If you do, you will be permitted to join. If you mess up, nothing will happen. And they type exactly captcha but nothing happened.
