My avatar on StackOverflow went away, and I now have a generic emblem.
Same thing for Meta
The two avatars were quite neutral, one was my hand on a computer keyboard, the other was a picture of bright yellow Autumn leaves on a tree. I seriously doubt that their content was a factor in the action.
I didn't change either.
What happened ?
Why did it haappen ?
How did it happen ?
What did I do to make this happen ?
What can I do to stop this in the future ?
I hope this is not a duplicate question. I did look at the top five similar questions, and didn't see this one exactly corresponding to any of them.
