BLAB posted this and several other photos to their Instagram stories and nobody seems to be pointing this out. I don't know where to go with it.
PhotoLayers is an application used to overlay photos on each other. The app icon being on an iPhone homescreen like this directly after core everyday applications suggests either a recent install, or frequent use. It has powerful crop and eraser tools that would be incredibly handy to say, change the date on a static image. I know this, because I use this app to make memes sometimes, and I used this app to combine this photo.
I took the photo into Photoshop and checked the image for digital artifacts around the "30". It looks as if the number has a distinct outline to mask out whatever was there. Zoom in for better view. Comparing it to surrounding text makes this seem obvious to me. I do not believe this photo was taken when they claim it was. I believe Spencer did not realize the very app he used to edit the photo was in plain view.
Other artifacts can be found in their other "test" photos, but none so obvious to me as this one.
The other scenario (the one they would have you believe) is that they took this cheeky photo a day before the Pirates reopening somehow knowing they would be attacked online, and kept in in their back pocket instead of leading with it, to dispel any concerns leading up to the day.
You tell me which explanation makes more sense.
