The Official UK Charts Company have been in touch with UKMIX to complain about unauthorised use of the midweeks charts information.
Apparently, fans should not be allowed to know facts and figures about the music they buy.
Personally I don't see how discussing the midweeks can be anything but a good thing. Taking copyright enforcement to the fans is at best short-sighted, probably a lot uglier than that.
Anyway, my opinion has no bearing on the law. Unfortunately, it's difficult to establish exactly how much discussion of charts is "legal" without paying up a fat wad of notes for proper legal advice. So I'm going to have to err on the side of caution.
I will need to remove/edit some posts in the Midweeks topic, now and probably again when I receive more information about alleged copyright infringement.
From now on, please do not post any chart information that can be construed as infringing copyright. This means specific chart placings or listings. The midweeks information should be considered more sensitive than regular chart placings; while it's probably ok to say "Madonna's at the top of this week's chart" after the weekly Top 40 rundown, it's probably not ok to say "Madonna's at the top of the midweeks chart" halfway through the week.
If you want to be extra safe, avoid thinking about chart positions immediately before and during a session on the UKMIX forums.
Anyone who posts midweeks info will be causing us a lot of bother, as we'll need to delete posts and respond to complaints about copyright infringement, so we'll have to (reluctantly) deal with it as other forms of forums abuse.
