1. Are people who do not speak english fluently not allowed here on SE-physics? (Since they may not be able to format properly or choose the clearest words). Usually i can understand what someone is talking about by context but ive seen complaints and closures.
2. What can we do if we are being harassed by another user(s)?

Ive come to notice some elitists and trolls that post comments not related to the physics question or ridicule others for asking a question they find elementary or uneccesarry.

How can we combat these behaviors?
