This is gold. This developer has a bold captcha solution.

bold as

h1 {
font-size: 100em;
font-weight: 900;
}

😂

I don't think this will really work...

It's a fairly standard tactic to filter out lesser bots called a Honey Pot.

However they should make the input hidden so it can only possibly be completed by a bot and not a user in error.

@corscheid very

@LynxMagnus too few upvotes here

A modification to this can be random chances of the input field to be filled or not. So only a human will understand if it is to be filled or not.
And a bit of assistance through placeholder

@LynxMagnus That used to work but bots are smart enough now to check if a field is hidden. So if anything this approach as bad as it looks is possibly better.

The real problem here is Bootstrap

@jackdh I use a text field with visibility: none;

Damn it, this is pure genius!

And have the name attribute name="address2"

That works well, although you normally hide it. The idea is a bot cannot read the placeholder text, so a bot will fill it in based on its type, the form submits successfully from the front end, but is thrown out by the api if the field is not blank.

@jackdh You're right that a Honey Pot, even when used correctly won't stop all bots, but will certainly catch a few.

You're security approach should be composed of many different approaches.

Hopefully these guys have implemented the others rather more successfully than this one.

It's called a honeypot, you normally hide the field with CSS, so only bots will fill it making the form fail.

@George1 I do that too, works like a charm.
