Security

No CAPTCHA? They tried

Usually it is not personal, but if your forms have no protection, it’s a matter of time until bots find them. And then this happens.

Wasted time

Cleaning up the mess, created by bots, tends to be quite annoying. Not only you will have to separate real users from bots, but also deal with backups and external providers.

Economic impact

Even if you’re not using serverless technologies, submissions by bots tend to come in dozens, costing you in bandwidth, database, and compute resources.

Service disruption

The largest public side-effect of bot abuse is, of course, disruption of the service that legitimate users rely upon. Don’t let bots to ruin the hard-earned trust.
