Is it ok to copy web content

[kkump]

It is legal or right or legitimate to copy and use web content from another web site?

[designerinside]

it is totally illegal to do that, unless the author gives your permissions to do that.

[HAWK]

It's plagiarism, which is effectively theft.

I think its ok if the author already gave his/her permission to the reader to republished their contents.

I think there are also citation clauses where you can use excerpts of content as long as you explicitly mark them as such and reference the source.
