There's a few occasions where players have been offside in an attack and the ball has eventually went out for a corner which presents a goalscoring opportunity.
Are these even checked?
If this practice is historically commonplace in refereeing it's a worry. Doesn't surprise me though as it's sometimes the case as when a contentious free kick/corner has been awarded the referee blows up for a soft foul against the attacking team.
Telling me nothing I don't already know. The PGMOL is completely pally/overfriendly with the darling six and will try their best not to give decisions in favour of the 14 scum clubs.
