@disney fcs: Honestly, it’s not the “Disney” or even “popular” faces to use, that bother me. What bothers ME is how the people who generally take these faces seem to only stick with pic-ships, start cliques, and are almost always carbon-copies of what that face claim played in their “show”. Right now, the craze seems to be with 1D faces - all anyone does nowadays is join, scoop their faces up, and plot the boys together as bffs and even as a “boy band” which is just… wow?
