Are there form/landing page limits in addition to API limits?

[Brandon_der_Bla]

I searched for a bit but while I could find API limits, I couldn't find limits for interactions with embedded forms or landing pages with forms in them. If there are no form/landing page limits, why is this? I feel like they could potentially be abused just like an API could be.

If we're switching from Marketo forms and landing pages to our own custom build forms and landing pages using the Marketo API, will we have to suddenly worry about going over all our API limits or will things stay mostly the same?

The forms endpoint is limited to 30 form posts per minute per source IP. (This is discussed in a few past posts.)

Naturally this makes forms orders of magnitude more scalable than REST API-based attempts. Consuming REST calls in response to individual end user activities creates a clear DoS vulnerability.

There's no formal rate limit for LP pageviews.

Are there any rate limits or restrictions for making Form API calls such as loadForm?  We are looking to poll loadForm for changed values in real-time, perhaps once every 30 seconds, but there will be around 2000 users on our site concurrently.  On a related note, is there a better way to grab the latest Form values from the server other than calling loadForm?  Thanks!

I don't understand the business case for this. Please explain in detail. Sounds like a bad idea straight away.
