You point out how petty it is to earn free credits but I would bet money that if they were available to you you would have a "huge" pile of them, anyone who can do the par 3 bug for xp points for weeks on end can't knock people doing surveys, how much did you make doing that...LOL ...That said spare me of any further analysis of doing surveys...
Sorry to pick you up any further, but I never said it's petty. I said it's not for me and the main reason is that I consider it to be paying ILLEGAL rates of pay. I consider such rates to be morally objectionable, and so I object and give warnings to those who may be unaware.
Now, if you or others wish to take part, that is, of course, your choice. I'm not in any way saying you shouldn't be allowed to do so, I'm an old-fashioned type, so do what you like so long as it harms no other.
