What they do with our database?

They create so many copies of your posts as a revision and increase the size of your database. Let’s take an example:

Suppose you have created 200 posts and we assume you have saved / auto save 5 times on an average to each post. Now the total posts will be 1000 into the database that will increase the size of database 5 times from the actual size.

Due to heavy update, many no of revisions are created and then affect the performance of the database.
