Maybe not an alt (who knows) but part of the same group according to ZKill.
Just do understand that it is against the rules to artificially try and up the bidding process. And this is that one part of the forums where CCP kinda has a really heavy hand.
I see this character from my past ally. He wrote in the topic of my main Character too.
IDK he whant to buy or this some kind of “help” .
But this does not mean that I ask him to do that ,and this does not deprive him of the right to bid.
If ccp have questions about my alt or not my alt, they can perfectly see from which account are posting and where it is regionally.
(Sorry for my english)
P.S. I’m not sure yet that I really want to sell, I’m looking at how much are willing to pay for them. If the price for both my characters is 220+isk I will think about selling.
