I guess you must have missed the OP, but let me fill you in. The premise is that both Vitor and Chael were caught with illegal use of PEDs. The difference is that with Vitor that was in 2006, whereas with Chael it was in 2011. And yet, people were quick to forgive Chael on his very next fight.
" Urinalysis conducted after his loss to Anderson Silva showed Sonnen had an unallowably high testosterone/epitestosterone (T/E) ratio of 16.9:1 at the time of the fight. An average man has a T/E ratio of 1:1, and testing bodies may allow a ratio as high as 4:1 for athletes undergoing TRT treatment. In other words, Sonnen's T/E ratio was nearly 17 times than a normal man's and over four times the allowed maximum for an athlete.[23] He was fined $2,500 and suspended for one year (until September 2, 2011) by the California State Athletic Commission (CSAC).[24] His scheduled rematch with Silva was subsequently cancelled.[25][26] "
