Using irrelevant tags, especially popular tags, makes it hard to find good and relevant content.

Please try to use only relevant tags when posting.

#photography
Please refrain from using #photography for posting art, posting graphics, posting other people's photos without proper attribution or explicitly stating it's not yours.

Not citing the source of photos (images) is plagiarism. Here is a post on why this is bad, and here is how easy it is to find allowed photos.

Not indicating that the content you copy/paste is not your original work could be seen as plagiarism.
