There have been some harassment and bullying here on Steemit but not to the extent that they jeopardize the whole community members and Steemit itself. Isolated cases. But overall, I believe people in Steemit have behaved properly.

I have made a series of Steemit Etiquette blog posts. Vulgarity and profanity is in fact next on my list.

If you have time, here's my latest on this series.
