180 days is more than fair. I know I worked at a job and somehow my last paycheck was never shown as cash so I had to work with them to get it reissued and cashed with a certain period so they could have their books balanced.
But I've made around $6 in a day just from surveys so if you haven't been on the site for a while you would have many more free things to complete than someone who is frequently on. I would actually try to put in the effort to make some money instead of just complaining how unfair it is. If you really think that the expiration period is so wrong then work to earn enough to cashout then leave the site.
I'm a veteran "GPT" site earner and I'm fully aware of how these sites work and how to earn. And I work plenty hard to get the money and gift cards I earn, which is a LOT, by the way. I have every right to make conversation about the expired offers and express my opinion of not liking a company to keep my earned portion.
I really don't think your so-called advice (more like a lecture) was very productive in the art of constructive suggestion. It was more like a rude comparison to your life and productivity in which you and I are not the same person. Also, you act like it is so easy to just whip up a fat daily goal every day by doing surveys. Good for you if you can earn $6 a day just with surveys. Not everyone is given that many surveys and even when they are, not everyone qualifies to take them.
I will reiterate my initial complaint before - I do have a life outside of the computer and outside of FC that many times takes precedence over other things. And sometimes those things are very serious and important that it is impossible for me to ignore. So don't act like it's so easy for anyone to earn a few bucks when they have a new baby, lose their house, have their internet turned off, are dealing with legal issues, start a new job, have other hobbies or responsibilities, etc. People have lives and they live them regardless.
Honestly, if you can't be polite or refrain from having a sarcastic, self-righteous tone, you should just keep your inner commentary to yourself.
