Can you help to identify these frames, bikes or parts?

Well, I concluded that it was pretty likely that you have another account on here. But couldn't conclude that it was absolutely certain.

As in, ignoring sentiment of the comments, the other account has similarities in network and timing and other signals that the software didn't answer "these are totally unrelated"... it drew some correlations between the two.

But... the software didn't come back and say "it's definitely the same person"... which means I'm left thinking, it's a strong possibility, it's likely... but I cannot authoritatively state it's definitely a spoof account.

Then again... the software is just software... it's given a likelihood, it thinks it's possible... and then one reads the comments, and as a human I tend to think it's highly likely given the sympathetic sentiment of the comments of the other user.

But hey, this is just sigint, it's fun. I can't prove you have spoof accounts in this case, but I can't disprove it either. None of us are wiser for it. It is what it is.
