Is it legal to spin the article?

It depends on how you use it, the best way is to combine spinning and crafting.

In my opinion, yes, but it is.Not everything is professional.It takes a long time to create unique content, but it makes for a better recognition.Without recognition, there may be very little sales at all.

I would like to say that it's not legal as it causes the spamming, as you have asked, is article spinning legal?On a daily basis, search engine algo are on high mode.It will affect the website where it will be posted and it will capture the spinning content.

There are so many content writers who can write about your topic.

This is also known as churnalism, where someone takes material, re-writes it, adds a few new photos, and presents it as their own.Since they don't have the time or resources to create their own material, many websites use this.As websites compete for eyeballs and content, it is unethical to do so.They fail because smart readers catch on.You can read about this time in my book.

It is unethical for article spinning to give the impression that someone has done a lot of work when in fact it is not.The contents aren't worth anything to the reader, but they are worth something to the marketer.
