If you write the /discord broadcast command with a message starting by a #, the hashtag will, by its nature, hash out and prevent the message from being sent, leaving the command executor with "No text given to broadcast.".

It probably thinks you are trying to put in a channel, for example /discord bcast #some thing it would try to send thing to the #some channel

Try specifying a channel, for example /discord bcast #general #something

I just tested it out, I do find that it identifies #some in /discord bcast #some thing as the channel it tried to send to. You are right about that, this may cause issues in the terms of user experience, its a pretty minor thing, but never under estimate small issues. Perhaps they should add an option to perhaps send things like /discord bcast #OMGTHISISCOOL >> #some and it would send #OMGTHISISCOOL to #some as signified by >>, just something setting things apart.

Having the >> as an alternative to specifying the channel at the beginning would needlessly overcomplicate the code & literally never be used
