You have interpreted 75.128.47.18's question as being about the TOU, when their question makes no mention of the TOU, nor any indication that their question is about the TOU.
 * 75.128.47.18 asked if editors were allowed to delete things from their user talk pages.
 * 75.128.47.18 did not ask what the TOU said about it.

As 75.128.47.18 did not specify any particular wiki, it is impossible to be more specific, so the only relevant answer is: Whether an editor is allowed to delete things from their user talk page depends of the rules of that particular wiki.

That may be your definition, but that doesn't make it fact. If you would like to assert that this is fact, then the onus is on you to link to where Wikia Staff have specified that wiki admins are not permitted to create "rules" and are only permitted to create "guidelines".

Luckily, I've had many discussions with Wikia Staff in the past about what fundamental rights users and admins have, and they commonly use the word "rules" to refer to "things admins can create and enforce"

In support ticket #99265 about this very topic, "Do User Pages/Talk Pages and Message Walls belong to the user?", semanticdrifter said "Some communities have strict rules about what can and cannot go one those pages, while others take a much more laissez-faire approach and consider them to be the "property" of the user.", which tells me:
 * A. Individual wikis are allowed to make "rules".
 * B. What users can do with their user talk pages is up to each individual wiki.
 * Obviously, admins cannot allow something that is already restricted by the TOU, but that is not what this question was ever about.

In support ticket #196515, Sannse said "[...] is not something we remove rights for, nor is being strict with a wikia's rules." and "I see that [redacted] did not keep to your rules and, as I said, I accept your right to ban him."

In support ticket #6054, I asked said "are admins allowed to make rules? [...]", to which Brandon Rhea replied: "[...] admins can set their own rules"

In support ticket #88367, semanticdrifter said "However, such a policy could be a local decision and if the community wants to institute such a rule for that particular wiki, they are free to do so."

In support ticket #7058, Tim Quievryn said: "We have said a number of times that "We strongly encourage wikis to create their own specific guidelines and rules that fit their community and topic.""

In fact, http://community.wikia.com/wiki/Help:Community_guidelines still says: "We strongly encourage communities to create their own specific guidelines and rules that fit their community and topic"
