This happens without fail every Triodion, and is nothing to worry about.
The cover of the Book of the Triodion is somehow tethered to a trapdoor in the Abyss where special Purple Demons are kept whose job it is to sow trouble, misunderstandings, anger etc during the Fast. As soon as we open the Triodion on the Sunday of the Publican and the Pharisee, the Purple Demons are released, and, most notably on this forum, trolling increases. "Troll" is a verb, not a noun, and refers to a fishing technique where multiple long fishing lines with multiple hooks are dragged behind a boat to hook as many fish as possible, so of course, with the advent of the Internet, this technique is encouraged by the Purple Demons on Orthodox discussion forums to trap as many of the faithful as possible and destroy as many good fruits of the holy season as possible. The trick is not to take the bait, and to trust in the triumph of the Resurrection. Mark my words, I have watched this forum for six years now, and it happens every year. At the sound of the first Bells announcing the Pascha, the Purple Demons are sent scurrying back to the Abyss to await the next year's Triodion.
