Regulations, attempts and impacts:
The PageRank module code should be inserted without any modification especially effective for the backlink! The Camelpark PageRank module used without the backlink will display "Removed backlink!" error message with no functionality.
Use one and only one PageRank module on your frontpage - only for displaying your own site's data! Attempts for using multiple PageRank modules on one site (one page) like topsites or references pages will result "Banned domain!" statement.
More info: The first PageRank module show-up happens in 3-6 sec., then there is no no response time or very little. The measured figures refreshed in every 12 hours in the meantime the module downloaded from cache.
