Being fooled
There are a wide variety of skins but the skins'prices are often unreasonably high compared to the price in steam market.Surveys seem like a sustainable and time saving way compared to apps but you will soon get "banned" from surveys.Take yuno surveys as an example,you do a lot of surveys in the early weeks and it knows you like surveys.After that,when you have finished a survey,it starts to say "this survey is not a good match" as an excuse of giving you no reward.Actually the surveys will kick you out if you are not qualified after you have answered some questions wrongly but not after you have finished the whole survey.So ridiculous!
