Hello, I am a tester on amazon.fr there with a lot of competition between tester, some person likes to vote "NO" on the usefulness of my test comments. I wish I knew, even by cheating, so there a possibility to increase my "useful" vote is useful and resume my percentages. Or simply if you can do me a service is put "YES" on my votes. If people want to do well, you could pm me? I can pay small amounts. Thank you in advance and I wish you a good day!
