I still hate that I have to follow these in order to block them. I know I can still unfollow them later but it's annoying partly because it makes them successful -- successful in that I do visit the blog and might see their advertisement.
Maybe someday booklikes would add a block option right on the blog or on the notification that someone followed you versus making us first follow someone.
It would be lovely if some time booklikes would either run a script or make a menu option so we could check for in our "followers" that would show profiles with only one blog post plus zero books shelved (or at least those that have been here a certain period of time with no activity beyond the one blog post and following people).
Maybe booklikes could also take a look at profiles that were frequently blocked if they have those statistics.
Both options might lead to cleaning up spammers.
