If after all the work done and all the connections found you don't find it enough for a tag, what is enough for a tag, according to you?
More sufficient evidence that connected them beyond reason of doubt, at least according to me in my head. Like, this is much more damning as its simple address recycling between alt accounts:
Hello OP.
I want to ask if these two users can be considered alt (gunhell16 and Mr. Magkaisa)?
Because based on what I saw when Mr. Magkaisa replaced his Bitcoin address in the
Duelbits campaign topic (when he was still a participant in the campaign) I also saw that gunhell16 had also posted the address in the WINZ campaign and now he has also become one of the participants in the Duelbits campaign. So can both of them have indications as alts?
...
Yes, there's quite a lot of evidence here that you've collected which says they are alts. I don't have time to look at it right now but am leaving this as a reminder to myself.
