Well I realized some guy is using his penance glyph ( http://www.db.pandawow.me?item=45756/glyph-of-penance ) behind pillars, so that means Penance is as same thing as Toss, so can a guy be banned for that situation ?
-In short words, he casts one charge of Penance in front of pillar then the 2 charges behind pillar which allows him to avoid silence
