I got asked about him, and yeah he's basically offering spam and other dishonest services, in so far as fake likes and views are dishonest.

I don't think what he's offering here rises to the level of deserving a negative, though.  If he did indeed offer something like an ICO bumping brigade, then it'd be a different story.  That's my opinion, but I certainly would respect someone who didn't view it that way.  Ludji is kind of a miserable little troll, looking to do the easiest job in life behind a keyboard--very much like bounty spammers do.

Everyone should be wary of these things that can be manipulated online, like product reviews, likes, eBay trust, and all of that.  I tend to be very skeptical, but I'm sure lots of people take things at face value.
