My family time shifted Christmas one year to deal with divorce related scheduling issues. That meant that, as an adult, I would be alone on Christmas but that the family would celebrate Christmas later.
For me, it wasn’t a big deal since I would be able to celebrate Christmas, just on a different day. It was hard to get co-workers to understand it.
I don’t know your friend. Your friend may be ok if she has a Christmas with her kids at a later date. She may be depressed enough to not want to talk to anyone so she could pretend it is just a normal day. She may want Christmas with friends but doesn’t know how to communicate it.
If your friend told you that she wanted to spend Christmas with anyone, I would agree with you. However, given the circumstances, if you are really worried about her, just call her on Christmas, wish her a Merry Christmas, and let her guide the discussion.
There are some subs on Reddit dedicated to finding botnets on Reddit.
By now, there are a wide variety of reasons to have a botnet, mainly tied to curating some public opinion.
