We can't really blame Sylon in this case because the maybe Sylon also didn't get paid from this jinby project, but it is very unfortunate if Sylon disappears after this jinby project is finished and until now, it seems that Sylon has never updated its telegram bounty channel and as I recall if sylon handles a last project called windhan and I don't know what his fate is now 
even though we know Sylon is one of the best bounty managers ever in this forum.
