Validate user subscribe form inputs before creating entry

ℹ️ Support

We have been experiencing spam Newsletter sign-ups for the passed few weeks. The users getting signed up have a valid email address, but the rest of the data on the input form is just garbage. For example:

Subscribe page: 1
First_Name = 2
Last_Name = KXZslijM
Address = aJuWQpXnKodIlAVr
City = zxgYLPpJ
Zip code = sugGbSXTZQeD
Phone = ToQEqUwHkxOAPSRn

Is there a simple way to add validation on the data to help filter out this garbage? I’m thinking something on the Zip code field - it has a fairly easy format that could be tested.

Thanks,
J
