Second, I have no idea what you're talking about. The submitter seems to have exactly six submissions so far, and not a single other one about this. [Edit: Obviously mistaken on that point]
I don't know who's submission history you're looking at, but zzaner's history shows 4 of 6 links pointing to nuclino.com and a 5th is a link to Nuclino for iOS. Only the 6th seems to have nothing to do with Nuclino.
