You simply don't pay! How do you mean, 'What can I do?' 

What do you need to pay for here anyway? 

'Answers' part of the website is free, as I know.

You can post and read free of charge ... since ... long time ago. 

You'll even get pints reward, what you can exchange for raincoats and umbrellas and more ... of rainy items, 

Click 'Redeem Points' and you'll see a wide assortiment of rewardz ...

There's no real need to get the paid version.
