0, and when people approach me with names for sale and they cite some inflated bot value, it detracts from the amount I'm willing to pay, it's a strike against them because I just assume they're trying to bamboozle me. It hurts the credibility of the seller, in my eyes, to cite ridiculous automated valuations.
Also, it signals to me that they have very unrealistic expectations, so there are times I won't even bother making an offer on a name I otherwise may have been interested in. Now that I think of it, this happens fairly often. There was an okay 4L listed here the other day, but the seller made a huge deal out of pretending it was a real word, talking about how they think it's worth 5 figures etc, so they kind of shot themselves in the foot in terms of getting an offer from me. Which is fine, if they genuinely only wanted xx,xxx for it then it saves us all some time - but if they were just trying to pump the name up, it had the opposite effect.
There have been plenty of names I've been interested in but if someone's telling me they think their 3 week old handreg is worth $2000 according to this or that, it's hard to even get to the table.
So, I guess I actually assign negative value, less than 0.
Just my 0.02, tho.
Edit: I hope the results here are eye-opening from a seller's point of view, nobody cares about these tools except the registrars who sell a bunch of janky domains to newbies who think they can turn $8 into $2000 because some robot told them so.
