All scrapbeox does it to generate http requests to servers, in the same way a a web browser does when you click on a link.
Cable companies do not care about the number of connections being made from your line, unless it was having a degrading effect on their network, or you were running something like slowloris.
There is no conceivable way which I am aware of which would show scrapebox http requests as being part of any p2p network. Neither by limiting ports (To do so would mean limiting all connections to webservers on port 80, which would be a seriously unwise move on the part of any cable company), or by deep packet inspection (which would only return the result that they are standard http requests).
I have no idea which cable company you use, but I know that my own one degrades my connection if I go over a certain usage at certain times of the day, so I plan to do most of my scraping overnight, when no restrictions are in place.
It could also simply be that your local cable service is suffering from a high demand at certain times of the day, pushing the contention ratio over and above that which provides a decent level of service for you.
