I think @honcho might have hit the nail on the head. As suggested by @easygoingpal I used a variety of different sources this week for a number of my GIFs as one of my main sources seems to be drying up. There is as we know pressure to shut down certain sites. So perhaps that’s what happened...
Also, and interestingly, when preparing the previous week’s TGIF sequence a number of them disappeared before posting them. In that case I knew that there was a problem so there’s was no attempt to try and post anything This week it happened after posting. There is something strange going on with XXX material.
Interesting to see if the PG pic posted below shows up!
