I had a look at this, and have similar results, but I also notice several errors from the page, which lead me to question the validity of their test routine.
Code:

Are certain ports blocked for all traffic?
3 out of 3 control flow transfers on port 6881 failed to upload any data. It seems like your ISP hinders you from uploading control flow traffic on port 6881 to our test server.
3 out of 3 control flow transfers on port 39516 failed to upload any data. It seems like your ISP hinders you from uploading control flow traffic on port 39516 to our test server.

Is your upload traffic rate limited?
There is no indication that your ISP rate limits your uploads.
However, some of the measurements were affected by noise, which limits Glasnost ability to detect rate limiting.
Details:
* The measurement data is too noisy to detect whether your ISP rate limits your BitTorrent uploads. Re-running the test while ensuring that no other downloads or uploads are running in the background might fix this problem.
* There is no indication that your ISP rate limits uploads on port 6881 or 39516. In our tests, uploads on port 6881 achieved up to Kbps while uploads on port 39516 achieved up to Kbps.

I don't limit ports on the Subscriber Management platform, but there is always a possibility that ports are blocked deeper in the network. If someone is legitimately having a problem with a port then please call the support center and log a call accordingly.
We all know that BitTorrent and World of Warcraft downloader
work... both use port 6881:

I can't find what port 39516 relates to ... if someone is using this port and cannot use it, call the support center and log a call please.

We are in the business of selling bandwidth after all, why would we block the ability of using it?
