It has always been the case that a user could /msg the gods to ask for re-owning a node. Do you know how often that ability has been exercised? Like, about once in 25 years. We want to make it as easy and obvious as possible. If you don't need it, you can ignore it. If you don't need it, you can hide the link by styling p.claimit in CSS.

they just click&error thru everything. And many bots are even worse.

Newbies we can handle. Bots won't have access to it.
Anyway, if that turns out to be a problem, we can address it then. Until then... don't worry about it.
