SideburnEtic  filed a deletion request for popcorntime :
With worries of association with popcorntime.sh (viruses, ulterior motives), whether or not the allegations being thrown around are true, the site is blocked by my university (unlike several other PopcornTime forks) as many people won't read the comments before trying to 'build' this.
Request #5101 has been rejected by Muflone :
I personally opt to deny packages like popcorntime in the AUR. However we cannot solve the maintainers discussions, please discuss with the package maintainer.
