One way to anonymize voting, if desired, could be just make a mess out of who voted what in the logs. I vote something, some other random user’s name is logged. Or maybe that could be used to deter scrapers and make the incorrect logging reverseable somehow that requires actual human interaction that cant be automated.
dont buy crappy products. Some companies are simply too malicious and should be avoided. Convince others to do the same and tell others and it might even have some impact.
