I have made more than 2,000 edits on Wikipedia and usually talk at user talk pages both to welcome users and to prevent vandalism. The left sphere-shape at the corner of my userpage means that I am autoconfirmed and the other one is the extended confirmed right. I may be lurking sometimes so that's why I edit pages all with totally different topics at a time. Another reason is this vandal tool here that I use casually sometimes: User:Lupin/Anti-vandal tool.
