I didn't post much for a couple of months but have been more or less active since the early days.
There was a disaster with my following. I was looking at someone's profile and clicked to see who they had blacklisted. This was way back when those options first appeared and my whole list of people I followed got wiped. No one could explain it but I had to start following people from scratch. I was quite miffed because as you say, I like to catch old people when they turn up again
