Hey there
I believe this is a good feature and save us a lot of time to to those thing manually.
Follow pre-action: Randomly like/comment on some user's posting before following him.
I did found a pre-action option under the Like tab, but I think this feature is not good:
1. It needs specific url of each post, which takes time to harvest.
2. It does Like only (no comment. I am not very sure about it)
3. That user maybe not in your follow list. Even it does, you might not do the like/comment at the same time. It might be like, follow today, and than like tomorrow.
I suggest the new pre-action placed under the Follow tab, with a percentage option. It pick up the user's posting randomly and do like/comment. Benefits:
1. More focused. with the like/comment and follow together, it might cause more attention of the targeted users.
2. Save lot of time.
3. More
I know some other script (not for Tumblr) integrate this feature, it even doesn't need us to setup.
How do you think?
