Lord Krishna I seen this also for one profile..
But I don't find a reason they get blocked.
Is it means I blocked by them? But why? I don't have a conversation with them..
I don't guess a reason, for they get block..
Besides the 3 reasons I mentioned, one can also request to have their profile deleted.
I cannot say why. it could be due to any number of reasons.
Feel free to ask via feedback. But, they may or may not reveal the reason Jayakrishna🇮🇳
