Note: there is another report for two other sockpuppets at Wikipedia:Suspected sock puppets/Mattisse.
User:Mattisse has already been confirmed as a puppeteer, see Category:Wikipedia sockpuppets of Mattisse. In particular, many of these puppets went around tagging articles about pagan authors with multiple tags.
Another thing the socks did was to create intentionally non-notable parody articles on pagans, such as, for example Anne Hill, created by sock Flinders, Modern occultists also created by Flinders, Charles Gatewood, again created by Flinders. Joi Wolfwomyn, again created by Flinders. There are several others. Another sock, User:NothingMuch started a semi-hoax and/or duplicate article Headingley ground. Suspected sock LiftWaffen has created a duplicate of Anne Hill at Ann Hill, this was the user's first edit.
Now LymphToad has done two things which match Mattisse's agenda.
Several of Mattisse's puppets complained vocally on Talk:Association for Consciousness Exploration, Talk:Starwood Festival and Talk:WinterStar Symposium about these events being "a group of thirty friends" and she and her socks followed all the links of speakers and performers, multiply tagging the articles, too numerous to list here. In short, this looks like more WP:POINT games by Mattisse. -999 (Talk) 20:51, 5 September 2006 (UTC)[reply]
Looking at article creations etc., this is an obvious sock. Iolakana•T 17:39, 7 September 2006 (UTC)[reply]
