People don't like the answer, but there's only one: anonymity. Any other solution simply changes who will be discriminated against.

Was it the picture or just bots picking up on activity changes?
I agree about anonymity though, it's the only solution that adds a degree of fairness.
People are really biased creatures. Usually the intent is not malicious, but rather caused by tribalism, evolution, empathy, mirror neurons etc.
One example is ageism, which is actually a systematic bias. For examplem to be a president you have be 35 or older. Let's imagine we created a perfect candidate in a lab which is 29. She's creme de la creme. And we have abolished this law.
No dice. She would not win.
