I kept my profile but painstakingly deleted everything I ever contributed in my profile. I think I did it in response to something posted in HN about some data breach with Facebook or something. I wasn’t affected it turns out but I did it just as a precautionary thing. I kept the profile around just in case I wanted Facebook credentials for something down the road. I was able to attend a webcast once using my account that I wound not have been able to otherwise.
