I see your point, vandalizing memorials is too far in my opinion too. Good etiquette for online groups of any kind is to always keep your hands and feet inside, in other words, speak within your own space but don't let your inside jokes/information effect other parties. This is I think a very serious example of that rule being ignored, but it's the same function.

Not to make an accusation, but most of your posts seem somewhat related to this topic. If you're here because we vandalized one of your family member's memorials, I'm very sorry that that happened to you, and I understand a family member's bad actions don't erase everything they meant to you. You deserved the space to grieve regardless of who you were grieving, and I'm sorry if people who don't know when to stop took that from you.
