If someone is being inappropriate on the site, whether through personal attacks, unfounded accusations, crass language, or anything else that truly is not in the professional, scientific spirit of the site, you can flag review or comment by clicking the flag icon beside it (see example below). 

If a specific user receives enough flagged reviews and/or comments from enough different users, it could be grounds for being banned from the site and their profile tagged. Conversely, we monitor who flags what - if we notice user is indiscriminately flagging things (or seems to be targeting a particular person or group unfairly), we reserve the right to do the same to them.
