I vote for all DEVs to work together - implement a standard exit to all applications in the Open SDK which clears down the various log files.
Preferably this should be in the open SDK in a location which is always called when application exits (I'm assuming there is some class inheritance here, but haven't looked into it much). Otherwise a standard function should be added that can be called anytime by devs.
I'd recommend a clear down on START of application as well as application EXIT. It still isn't goign to be 100% - since the "report back to us" might be triggered during runtime.
The best solution would be a custom firmware that has been modified to remove all of this shite - but don't know how likely that will be!
If i had more C/C++ & PS3 internals/SDK knowledge i'd put something together, but i don't so i'll just leave this post for the real PS3 devs to look into.
There are a lot of things they could ban us for at the moment, because we just dont know how deep they can check right?
So the safest bet would be to just give up on the online aspect of the PS3 until some crazy guy figures out something to keep yourself safe. But even then I wouldn't give it a 100% safety rating. At any time, they could figure out how to get ya.
Sorry if this has been said before, because I didnt want to read all 6 pages.
