While reblogging someone’s post is often meant as a compliment,reblogging all of someone else’s posts seems excessive.
It is better to write a piece about a blog you admire and then put links to the posts so that people read the posts on the blog of the person who wrote them.
You need to be careful not to plagiarize.
Reblogging images may put you in breach of copyright also.
As we are taught
Moderation in all things.
That is a good policy otherwise you give the impression you have no ideas of your own to write about so why do you have a blog at all?
Surely nobody has a blog just to put posts there from someone else’s blog?
You can teblog this if you like
