★★★★★ Serios petition portal

Serios petition portal. Good platform for trustworthy civic activism. All campaigns are carefully verified, and the user interface is easy to navigate and easy to use. The technical support is timely and easily available. Have a nice day.

★★ pay wall only?

In former time they had quite good ideas. The new business model seems to involve to force users to pay for taking part in any petition. I found no posibility to contribute without paying. So in the end they only aggregate user-payed data and send the result to authorities as "petition".
