Well, if they were real bronies, no troll or spam attack would faze them. Deflect, absorb, love and tolerate. The problem is a lot of supposed "bronies" on 4chan are more like pony proponents (proponyents?), and to make matters worse there are several distinct varieties of these proponyents that were previously separate, and don't really mix well. At least, that's what I understood from scanning the comments on the matter. Trollbombs dropped in the midst of such a mixed-values collection of people are going to be pretty effective.
