All signs point to no.
While Bandaged BD does indeed violate the Discord Terms of Service,
Discord has not been seen to take action on users for the mere usage of Bandaged BD.
Of the (estimated) over 20 thousand users of Bandaged BD there have been 0 known cases
of Discord banning someone just for using it.
As long as you stick to plugins you obtained from the #official-plugin-repo channel
in the BetterDiscord server
you should be safe from being banned.
Latest Statement
The latest statement made by a member of the Discord team
matches what is stated in the Terms of Service regarding punishment.
QUOTE (From the Terms of Service):
The Company reserves the right to refuse any user access to the Services without notice for any reason, including but not limited to a violation of the Terms.
The statement essentially says
that they reserve the right to choose whatever punishment they'd like,
including no punishment, however saying that they will not
punish ToS violators would be like saying they do not enforce their own rules.
