Possibly Microsoft too
I'm having an interesting thing happen with my Live account, only used for Visual Studio 2017. After a few months of a new Live account, suddenly it's blocked for "Potential Spamming", and I have to unblock it. To do that, I find out I have to add in my Date Of Birth and my Mobile Number...and when I get in there the account says it's brand new and has clearly not been hacked, or used for anything other than running and registering VS2017 Community Edition.
As a result, I defend against what I see as a clear attempt at a data grab by creating another Live account every time they "Ban" me. Basically if a company isn't going to be forthright about what it's planning to do with my data, I try to give them as little as possible. So all hail Homer Kwyjibo (just deceased) and my new alter ego Marge Samson.
