How to remove Facebook info from another website?

[Bond007]

I signed into a website called Pubble ( https://www.pubble.co ), with my facebook account, so I could ask a question on another website. When i asked the question on the website my full name and facebook profile picture comes up beside the question. How can I either remove all my Facebook info from Pubble or Delete the question through Pubble? Thanks in advance!
Where do I find "linked accounts" on Facebook?

Go in your Facebook settings to "linked accounts" and you should be able to disconnect "pubble" or any and all Facebook info sharing with other partners in crime.
