Sorry to burst your bubble R-flex sweetheart.

But you dont know if this was his friends base, which means that this is a valid building sign.
Nonetheless, even if it WASNT his friends base, what GMOD troller did was still rdm. Gmod could've made an f1, to be sure that this was NOT the case, but instead he took it upon himself to RDM a building base. Therefore he should be punished for it.

- Gmod you should really stop breaking rules buddy.
