While I can't vouch for the verisimilitude of this drama as a whole, I can confirm that Guy Fawkes and Everlasting are the same person, and are also the same person as someone who attempted to use similar tactics on me a while back under the name Stalk3r.
I have three of the listed BL_IDs in my database, as well as an additional linked BL_ID 84363. 18955, 37985, and 84363 have all connected to my server under the same IP; while 41403 has not, it has connected to my server from the same physical location, making me strongly believe that it is another alt. I've updated all of these keys to link to each other, and have also updated their name histories.
