If these accounts can be confirmed to be his alts with 100% certainty then maybe that qualifies as spam worthy of being removed, maybe theymos could chime in.
IIRC there is strong circumstantial evidence but not 100%. Theymos and/or cryptios might have more to go on.
On a side note, does this really matter when his flags will never get activated since he's not on DT, and even if they are supported by anyone, they can simple by removed from DT?
This already happened all the time in the old trust system.
Kinda sorta. With this new lottery-based DT1 you never know when someone might include him or one of his (possibly not yet known) alts, and the flags aren't as visible to regular DT members as the old red trust used to be - merely a "#" next to the trust score. So I went through those garbage flags and opposed them all just in case, and Foxpup did the same.
