To weed out renters, sqatters, or anyone who can't make a legal finacial desision about the certain property.
After a user creates an account, he/she can click and drag stickers onto other users' images. The default stickers include...
...a blue smile, "for things that make you smile"
...a red frown, "for something so awful... and yet... you kind of like it"
...a monocle, "reserved for all things classy, intelligent, or eloquent"
...a green LOL, "for things that make you laugh out loud"
...a purple shocked face, "for things that amaze or surprise you"
...a grey question mark, "for something you'd like to know more about"
...a cookie, "for things that deserve a cookie"
...a pink heart, "for things that make you say 'awwww'"
When a user receives enough stickers from other users to level up, she/he receives the corresponding number of golden #1 stickers for his/her level. Users also receive three golden #1 stickers per day they log in. These stickers can be used to purchase "epic stickers" from the Sticker Shop. While users have an unlimited amount of default stickers (listed above), they have as many epic stickers as they have purchased and as many #1s as they have earned.
"Sticker begging", which has become quite common on the site, is the act of deliberately posting an image of something that looks like a sticker to receive said sticker. For example, if a user posts an image of a plate of cookies, he could be sticker begging for cookie stickers. If a user posts an image of something completely purple, she could be sticker begging for purple shocked faces, whether or not the image contains shocked faces.
Many newfriends may believe that canv.as has "celebrities", users who post often, are talented at remixing, have been on the site for longer than most, or receive a lot of stickers. There is no validity to these statements. However, the Canv.as Team, a group of web developers who work on the website, including moot, often posts on the site. If a user is a member of the Canv.as Team, he/she will have a star to the left of his/her username.
Canv.as has an unofficial IRC room on Rizon's server, called #canv.as.
