The UK has a petition website. It logs the signatory by constituency. Once a threshold os signatory has cross, the government has to respond and parliament will have to consider a debate on the topic.

And just because they respond, it doesn't actually mean anything will result from it.

"No more something!" "We have seen your petition. Fuck off, peasants".

And You can use the response as campaign material. Ultimately democratic governments are accountable to the people at the ballot box.

This exists only to pacify people and make them think someone has listened to them.

This is the relevant petition: https://petition.parliament.uk/petitions/722903. The government's response so far is "lol no"
