If I'm not mistaken, the official Portal servers will allow progression beyond just XP. It's the player-created custom Portal servers that don't which is a real shame.

How are the devs blameless? They were the ones who were supposed to have the protections in place to help mitigate this problem but it was clear they didn't. Thomas Anderson even went over this in an interview months ago with Jack Frags. He obviously couldn't reveal any details but they were aware this could be an exploit and said protections would be in place to handle it.
Obviously the cheaters are guilty of exploiting Portal with their farms but the rest of us have to pay the price for the developers lack of action to put protections in place to help prevent such behavior. There is a level of culpability on their part here for this particular problem and responsibility of EA / DICE to deal with such issues in their games. ....cheaters, hackers, exploiters, harassment, etc.
What gets me is that after the fact they implemented an XP cap that is based on minute by minute activity. However, they still won't allow full progression of Mastery, etc. Why they can't apply similar logic to those is beyond me. It would better than what we have which is nothing. ....except XP of course.
