I remember an interview from 2006, in which Dave and H were asked about the rumours that Jan's guitar wasn't plugged in. H said he hasn't heard of them and had no idea where they were coming from. Dave said that he reads online fora and chatrooms, and had a very low opinion on them as a rumour mill.
I wouldn't be surprised if the Maiden camp paid some attention to online communities back when the official website hosted its own public forum. But I think that nowadays, at least the guys in Maiden themselves probably won't care anymore. I could imagine that if you had a career as a public figure for over 40 years, at some point you just don't give a shit anymore about what people say, because you've heard it all before, from better people, thirty years ago.
