We are here to help Google Wavers!
Since the creation of our "savvy Google Wave users" group, in the early 2010, our two main goals were to educate users about Google Wave and to fight abuse on Google Wave. We have now embraced broader goals, as the Wave technology is now open-source at the Apache foundation, and as there are no more incivilities on Google Wave, since all the users left are passionate Wave lovers.
Nonetheless, here is how we could/can help with fighting trolls:
If your wave was attacked, please add wave-watchers@appspot.com if possible in order for us to investigate further. If the wave is completely broken, and you are not able to add the robot, then please create a new wave with the link to the broken wave, and add the robot to the new wave.
