Please refrain from criticising the fans/community of a fansite...

25 - Do not criticises another fansite, community, forum/board or it's members without proof. And even then, it is best to inform Staff and/or Admin first so that they can assess if it is warranted. Objective criticism of the content of a fan forum (eg. vulgar content, promoting KOs, full of spam or advertising, false news topics, etc) may be okay, within reason and depending on the context and purpose. We are all Transformers fans, so there is no sane reason why one would want to insult another over how they enjoy the same darn hobby. There is no such thing as rival forums if they are all Transformers Forums.
As an example - I was recently critical of TFW, Allspark and The Official Club for them disrespecting Hasbro's Hall of Fame Awards, by way of them publicly pushing Erector to win after he was nominated. That criticism was not against the members or fans, but of the site's staff and admin promoting/encouraging it.
