Hosting a PHP Pagerank checker script

Hello folks,
Will google ban my server IP address if I host a PHP PR checker script. The script will be used to check 100’s of pageranks simultaneously.
If google is against pagerank checking requests, is there any way to bypass the limitation ?
Nb: I use shared hosting.
Thanks in advance.

No. But I heard that they will not allow 1000+ request at once.

Have you read Google’s T&C’s surrounding this?

Yes, they will block your IP.

Most PageRank checking scripts pretend to be the Google Toolbar, which is a violation of Google T&C’s.
