Is it acceptable to offer condolences using LinkedIn?

[Seainasive]

A all? Ever? Not sure how it happened but the only contact details I have now for one of my cousins is via LinkedIn, and I know his father, my uncle, passed away a few days ago.

Is there ANY other option?

Do you have any other relative who might have their address?

No it's not.

Is there no other social media you use?

Any way of getting an address or number?

No FFS. Can’t believe you are asking this. It’s just wrong.

Thanks that is pretty unanimous!

no

I think it's okay, especially if that's your only contact. Keep it short and sincere - something like “I just heard about your father’s passing.
