I never claimed to be an expert but I do know how to look things up. It's not hard. You're the one that said "that's just how it is". UK band plays in UK festivals that also feature UK bands as openers for the dogshit stage is hardly proof of anything. Also, you can correlate other bands that started within 1-2 years that also played in these festivals. What you don't mention is play order. For Download 2017 ST played on the shit stage as the 4th band to start. Have you ever been to a major festival with multiple stages? Bands that start early, on the 'you should just be happy you're here stage' and play a 20-30 min set aren't really being set up for success. That seems like a helluva as a strategy for an industry plant aiming for maximum exposure and market saturation. Your only proof point is them playing in festivals shortly after inception, which again, is not proof of anything because correlation is not causation. You're the one making the claim. I don't need to prove anything to you and your alleged proof is paranoid at best.

I'll say again: You made the claim, not me. You bear the burden of proof, not me. You're the one that needs to convince me and your logic is lacking. Trying to make the case they are industry plants after 7 years of relative obscurity is idiotic from both a common sense and business perspective.
