I've never seen this alleged "suicide counter" on the website, though I've only looked at it closely in the past couple weeks.
The site owner posted this rebuttal to assignment of blame for these suicides, which I find compelling. For instance, the widow of one victim decried Vice News (one source referenced in the article) for using her death to attack Kiwi Farms:
The "suicide count" in question was in one user's mini-bio (the bit below someone's profile pic where they can put custom text - not sure what that's called). Keffals' claim that it's a site "feature" is deceitful and that multiple users had it is an outright falsehood.
