I was wondering if any of toi all fans of the wanted have ever sent fanmail to them and have received it back with whatever the asked for

Charmedgirl1996 had answered me question on what is the fanmail address for the wanted and i wanted to make sure if it is right because it seemed to me that, that address has been up there for a while.
Fanmail address C/0 global talent 30 leicester square Londres WC2H 7LA United Kingdom
