Hey jman, welcome to the unofficial iSketch forum :)
In my opinion, I'd say that it depends on how the phrases are written. I reckon that there will always be people in Acromania who will post rude words. As general swearing isn't against the rules unless it is directed towards someone in particular, the admins might not be able to do much. Although if the phrases that are generated by some players are offensive and/or rude in their own right then I'm sure the admins could take action.
Addressing your main issue, admins can't be in every room all at the same time so, in general, they may not readily come across this potentially offensive behaviour. There are two ways to call in an admin.
- - The effective way - Use your vote so that the admins are aware that you need attention. After all, that's what it's there for.
- - The not-so-effective way - Send a private message to an admin requesting assistance. The reason why this is not so easy is that you need to know the name of an admin for the PM to have any effect. Also the admin who you ask for may be busy at the time.
Hope this helps :)
