User blog:The real tenko/20 minutes, 20 parties added 1 person raid

Roaming around Habitica Wikia I've encountered something rather strange - it seems that one person added 20 parties of his/her own (as if that were possible to be in more than 1 party at a time!) in about 20 minutes.

At first I thought that this person just could not make his/her mind about the name of his/her party >.> and hence the 20 copies. Now I see that this person only ~categorized~ these pages in a 20 at once batch.

But clicking through these I've discovered that some if not most are obsolete:

Pages of deleted guilds: Habiticans searching for a party (without providing their UID!) - this activity should be carried on "Party Wanted - Looking for Group" and *not* on wikia: Guilds' advertisments without any information on their leaders nor on how to contact these guilds: I can of course be misunderstanding this, but how do single users intend to search for parties on a wikia? Especially without disclosing their UIDs?
 * Taxidermist
 * Procrastinators
 * Porn-Free Alliance
 * Shadow Clan does not provide *any* information on how to contact this person looking for a party, does not even disclose as little as this person's nickname;
 * Quietly Confident mimics the above mentioned ad but somehow manages to provide even *less* information.
 * Newbies are the best!
 * Cat fans
 * The Mystic Combatants
 * Resolution Collectors
 * Indonesia HabitRPG
 * @NightOwl, is "Weenie Hut Jrs." still your party?
 * Canadian Bacon
 * Mandalorians

Shouldn't the parties provide the contact info to the leader or any of the party members, so the party can be somehow contacted? Can the party be contacted using the party ID (if so, I don't know how, that's why I'm asking)?

Also, for the pages of deleted guilds - how can I delete them? Is it at all possible, or does a mod need to do it? If there is no guild, there is no need for the page associated with it, especially since these pages are just as abandoned as the deleted guilds were (that's why they got deleted).
