# Abuse Prevention

Limits:

* The current web rate limits can be found in the DMflow\.chat Features section. Except for Facebook Messenger and Instagram, which are unlimited through hosted mode, other channels are limited to a maximum of five messages processed per second.

Why Limits:

* Because the tokens, secrets, and verify\_tokens of non-hosted channels are mostly provided by tenants, they are vulnerable to malicious tenant attacks on the public endpoints.
