Global Test Market is a decent standard of what you're getting yourself involved in. Their practices are not any more or less shady or reputable than almost any online venue – survey or otherwise. Just like Facebook, when you identify yourself accurately with Global Test Market, you can expect them to use that information in any way possible to make a penny. The great news is they inform you and ask for consent first.
By filling out your user profile thoroughly, you’ll be able to make sure you get invites to surveys which are actually suitable for you. There are basic qualification questions at the start of each questionnaire too, to ensure you are suited to filling it out before you get going. And you can make the most of the huge Toluna community yourself too – if you want, you can create your own polls on the site to ask people about anything and everything! It’s a nice addition to be able to get involved and have in-depth conversations with fellow users.
