Of those, I think Falling In Reverse and Hawthorne Heights are probably the most likely but I don't think they're the only ones on there.
He listed 30 bands, so I think it's just a process of elimination and seeing how they line up on the posters
I think 100% Mayday Parade, Neck Deep, All Time Low (gross), Falling In Reverse (double gross), ADTR at least in florida, Sleeping with Sirens and Pierce the Veil are my only 100%s I think are going to come from that, I can totally see GWAR and Underoath being a 100% too. I am not sure if LS dunes would play it but maybe for 1 show. These reddit guys really need to stop trying to make Blink happen, I would eat my words with a golden fork if they were on the lineup.
They asked how many did they get right and they replied with either 18 right or 18 and two eyes so it can easily be seen as a hint to Blink 182, but based on the budget I can see why it is unlikely.
Have you considered it means 2018, referring to the 2018 warped tour lineup, meaning that you should cross check the Instagram guesses with the lineup poster to figure out which are right?
Underoath playing Orlando is the easiest call of all time lmao also the red square is probably ERRA don’t know who fits before them and also has an E name though
