<<He was dismissed from the clerical state by Pope Benedict, not SSPX.>>
That may be why Bishop Fellay's name is on the list of negligent bishops.
Obviously, the SSPX is not immune from the clergy sex abuse crisis. 
Occasionally people who don't know anything about the crisis try to parse it along ideological lines, as though conservative or progressive theology or pastoral practice are somehow predictive of aberrant behavior. They aren't: offenders and negligent supervisors are found across the ideological spectrum; they are found in every corner of the church and throughout the history of the church.
I asked what point, if any, you were trying to make because I didn't want to assume that you were naively suggesting that the SSPX might be somehow less likely to harbor offenders or to engage in cover-ups.
