If it is linked to the Internet then it'll be hit by crawlers. Their "trap" isn't any how many show up but how long each bot stays on their individual site.
The issue, as I see it, isn't that they liked his policies or wanted to move right. What the public wanted was change, some drastic move away from the system we have. The Democrats explicitly campaigned on maintaining the current world order.
So when we, rightfully, said that Trump will destroy America, may who aren't engaged with politics thought that was a good thing.

Your last sentence highlights the problem. I can have a bot that posts for me. Also, if an authority is in charge of issuing the certificates then they have an incentive to create some fake ones.
Bots are vastly more useful as the ratio of bots to humans drops.
