>>3 You certainly can. There are some restrictions on the
site (eg, posting rules, duplicate threads, etc), but there are no real rules on the
group. So if you think the Dollars should remove graffiti from walls, you can round up a bunch of fellow Dollars from around the world and do that! It's very open-ended that way.
The problem is, many people on the site will need everything planned out extensively for them before they can do anything. In the show, everyone in the Dollars were really self-motivated and didn't need much prompting at all to take action. In real life, many people are not like that. So it's a little more challenging. But still possible! People are doing it all the time.
