remove implication loose_socks -> socks
These are very often kneehighs (at the time of writing this includes 5 of the latest 6 images with the tag), sometimes over-kneehighs or occasionally even thighhighs (eg. post #829996 - note that loose thighhigh is used for something else entirely).
Given that kneehighs have not been meant to be tagged with socks for the last 7 years, and things going over the knee for even longer, and that these images are polluting the socks tag.
Some relevant discussions:
topic #4894 (making kneehighs and socks separate)
topic #3807 (agreeing what loose socks actually are for, which is a specific style of "sock" -note that this was before the above topic- with no particular reference to its length)
The implication appears to have originally been made with no discussion.
EDIT: The bulk update request #1507 (forum #143842) has been approved by @NWF_Renim.
