i had the same experience ZohnoReecho someone was pissed because i did finish the fate 1 time and he did start by insulting me and all, first report.
later i join a group for chimera, he was inside, he did get the lead and kick me out of the group and restart to insult me via mp.... second report.

the trouble is people think they are right... because it's annoyed them if is wrong, means they need to play normally without shortcut!
i will surely have a lot of enemy after this comment.

but i think SE need to use severly the ban hammer for make understand this people that find and exploit a shortcut is not welcomed!
