I'm kind of upset I have to make this suggestion at all, but I would really really appreciate if the blocking on LW actually functioned as a block.
When I block someone, which thankfully hasn't happened yet, I don't want them interacting or seeing my account AT ALL. They shouldn't be able to see my wolves, buy my listings (on FM and in the CA shop), view my forum posts in threads, or otherwise interact with anything directly related to me. Blocking users is a safety feature, and not having that safety or power to curate your own experience on the site WILL drive away users. I shouldn't have to make a new account if someone decides they don't like me/something I've done and starts harassing me by following me around in the forums, buying any of my wolf listings (and possibly renaming them horrible things), or otherwise making me feel uncomfortable.
The block function needs some SEVERE reworking, because just disabling messages and removing forum history between users is no where near enough. Time and time again people have been proven to make awful decisions and take awful actions against others. I'm sure that many of the older petsim (coughFRcough) players have experience with sour interactions, and I'm sure that more than a few have experienced harassment on petsites. Please fix the block function to make it functional.
