I don't think they've ever accused AK of editing screenshots. They haven't addressed his claims that they skipped and later fabricated bets, and haven't mentioned the way his withdrawal address changed.
Re. the bet skipping/fabrication they said that they increased the risk-per-bet that investors were taking without consulting investors (since fabricating winning missing bets required increasing the stake of the following bet to more than was actually allowed by the site, in order to make the balance work out).
Re. the withdrawal they just say they sent the coins to him.
Any attempt to probe further results in a "fuck you guys and fuck this forum" type attitude.
