i want to report buller89 , trollerik878 and derbigpr50 for swearing in the chatroom. It was like a war of Germany,Finland and Russia.

This is not the appropriate way of doing it

Isn't it a rule to not Name & flame?

Apparently not

Unacceptable behaviour can be reported to us, and is best not discussed publically to avoid nasty-ness.
But when making a report, always include some form of evidence, otherwise the report will be ignored. In this case screenshots would do.
You can send your report to us via https://www.lfs.net/?page=mailus . If you need to send us files, please still contact us through that form and wait for our email-reply. You can then send us your files as an attachment in your email back to us.
