if posts only have value for 7 days, then would it be an idea to repost the same post regularly or resteem them???

I would like an answer to zeropointman's question too? How about it can you repost or resteem a post?

I guess this doesnt work the way you want it to, because as far as i understand (im new here) there are bots checking for duplicate or very similiar content and they will flag you if they find it.

Also if you do that, you will upset your Followers.
