The old thread is still open, you could have posted there if you had anything solid to track Pips into this.
For Athertle: He got feedback regarding the issue on both accounts.
It appears that this person has a history of leaving feedback for his own alts.
It is recommended that you use escrow when dealing with this person.
alt of burgerkill, which is a purchased account. has a history of leaving feedback for his own alts, take ratings on here with a grain of salt.
Now what you're bringing foreward is that Pips left both those accounts feedback also. That was the main reason why he was suspected to be another alt back them.
But as pointed out substrata, thats not enough to start pointing fingers.
Just speculation but Pips might belong to him too. He has left feedback for both atherlete and burgerkill.
pips is a sold/bought account (refer to pips' trust feedback page), entirely possible. cant really point fingers
without solid evidence though.
As for a connection: The only address posted by Pips AFAIK is
12euutj3uhjX7FgGFZwh9GQandBnhujMLE.
There are transactions between this address and the addresses held by Athertle, but there isn't a transaction connecting those addresses in a mutual wallet.
