laravel-honeypot - Preventing spam submitted through forms

  •    PHP

When adding a form to a public site, there's a risk that spam bots will try to submit it with fake values. Luckily, the majority of these bots are pretty dumb. You can thwart most of them by adding an invisible field to your form that should never contain a value when submitted. Such a field is called a honeypot. These spam bots will just fill all fields, including the honeypot. When a submission comes in with a filled honeypot field, this package will discard that request. On top of that this package also checks how long it took to submit the form. This is done using a timestamp in another invisible field. If the form was submitted in a ridiculously short time, the anti spam will also be triggered.

The plug-in makes things very easy for you with a limited amount of setup required and standard xhtml and css classes in place to make changing the appearance super easy.What Happens When you call $("#someDivInYourForm").simpleCaptcha({...}) the plug-in will make an XMLHttpRequest (AJAX call) to the PHP script which will then randomly select the number of images you specify (or a default) and from those, one to be the "correct" option. The script places a hash of the image text of the correct option (and some random characters) into the session and sends back the hashes - as well as the file locations - for all options. The hash is placed in the "alt" text of the image tag, and when a user clicks on an image, its hash is placed in the value of the hidden input.

no-mention-spam - This very simple bot written in discord

  •    Javascript

If a user mentions more than 25 unique members in a single message, they are banned. The reasoning behind 25 users (which could be lower) is that no one should ever do that anyway, and the only instance of it ever happening is spambots that mention in the upwards of 50 users per message, as fast as they can. This disrupts the flow of conversation, and also attracts all users into the attacked servers, generally leading to more collateral spam. In extreme cases this could make the server go into "slow mode" for a while, where all operations are slowed in order for the server not to affect others on the same Discord shard.
