Maybe I don't understand how this message board works. I thought that if a poster is vulgar or abusive, then they get banned due to non-civility? That seems proper and allows all views and opinions to be expressed - as long as the poster is not threatening, verbally attacking or belittling another poster. Doing that is not legitimate discussion. But being a fan of another team other than UK, whether they attempt to "hide" that fact or not is relevant how?
These "troll" alerts are sophomoric. Every time I read a post where somebody calls another poster a troll and then whines with indignation with incredulity that the moderators haven't banned the troll, I think "is this really another adult"? It sounds so childish. I don't think the moderators should in any way try to identify "trolls" and ban them. I say man (or woman) up. If you don't agree with someone's view, express why you think it's wrong. If you can't, don't go crying to mommy to ban the troll.
