Web3Forms provides variety of spam prevention methods.

First of all, we do run a server-side spam check on all form submissions. So even if you have not implemented any client side spam check, you will receive less spam because of our server side spam check.

However, to block more spam, we recommend adding one of the following server side spam check. Please click on each guide to see more detailed instructions.
