You are watching a movie.
You are sure that they were deleted, and didn't just fall out because of not enough bumps? I have to bump my own thread every few weeks so that it doesn't get removed.
Also don't forget that the catalog is broken quite often in recent times, which means even if you see your thread not near deletion range, the catalog may be broken and show you the status of 2-3 days before.
Right now I think this is all a big hoax tbh.
I mean there are tons of 17s everywhere, which probably means Q team is in control.
In Italy there are skull + bones numbers.
No coincidences.
I still think it would be possible to cause injury using certain frequencies, but also fix things using other frequencies. See Tesla etc.
Plus: if you created 3 threads about the same topic and there was not much info in them, they may have been removed because seen as slide threads. Only create one and it should be fine, at least mine is still up.
