I entered a survey, checked my tokens, and they were the same.. Is it a scam?

Years ago I used the same thing to get free premium currency in another game. I found the ones that often rewards "free tokens" are the ones that require a credit card to try out a free subscription. None of the Surveys will likely reward you anything unless you have the right tools to block the popup survey that basically prevent you from claiming the current survey's reward. Try looking for ones that require you to download trials for games and such. There are a few of those that indeed work.

so yeah I didn't get tokens either, does it take a while or is supermechs just asking us to take surveys for no reason?

That's why I've never tried them, just seems too shady for me.

Although it is offered by supermechs. The free token service is another party. So if you want to complain about it, you have to find the information for personaly or supersonic.
