Can you delete your facebook comments from a group who banned you? By temp deleting ur profile?

I was in a band and gave them many ideas on their private facebook group page. When the kicked me out they banned me from the private group and i was not able to delete my comments from their group. The have been stealing and using those ideas ever since. Is there no way to delete them without access?

I'm sorry, no way... to delete it yourself, you have to be the member of the group with the account that used to post/comment in there.
Anyhow, as it already posted/commented some times ago, they already know/make use of it.
