Everything happens for a reason, so I hope you don't feel regret for too long.
One of the upsides of all of this, for me, is that I truly learned a lot about how "disinformation campaigns" are carried out. It was really educational and I'll know a lot better how to spot it the next time I run into it.
I think that all of us have actually learned a lot and though it wasn't supposed to be the focus of this forum, I believe that there's a reason for everything. Maybe this is something that we'll need to know at some future time in our lives.
