How many requests per day is OK?

Hi,

we have a website with several hundred user signups per day and about 40-80k private messages sent per day. Spam is kind of an issue :) Currently we use SFS to:

- check IP of the user during signup process and serve him a more complex captcha challenge if IP is blacklisted on SFS.
- check IP of "suspicious" private messages, such as the ones written by new users, containing links, blocked keywords etc.

We cache IP lookup results for 24 hours.

I expect that we should generate an average of 800-1000 HTTP API queries per day. Is this OK? How many queries per day is considered normal, if our website grows and we need more queries?

The reason why I like to use HTTP instead of DNS lookup is that we query multiple blacklists in async mode using PHP Guzzle client. Most of the blacklists provide HTTP APIs and guzzle makes it easy to shoot async requests to all of them simultaneously.

thanks!

Re: How many requests per day is OK?

According to the terms on the usage page here: https://www.stopforumspam.com/usage the API allows up to 100,000 queries per day per site/IP.

Caching certainly helps, and if you needed more, you could always download the daily list and check locally.
