"Find and replace a term crosswiki requires discussion, always.": What do you mean by "cross wiki"? "Because things can be botted rather than polluting Recent Changes with tons of needless edits.": What do you mean by "botted"? How was I "polluting" Recent Changes? How were they "needless edits"?
"You've just come back from a year's block.": I know. "You're on parole.": What do you mean by "parole"? The block is over! Where does "parole" come into this? "That means, don't do the same stuff that got you banned.": Remind me once again what that stuff was? We may have different understandings of what that exactly was.
"Changing a term across the entire wiki. Needs discussion.": For the record, I haven't placed deities in every instance of gods. Have we discussed it enough yet? Why do we need bots in this situation, when a user can do it themselves? They weren't minor edits. That is why I gave them an explanation.
You've created Corrupt Officials four times now - though I clearly recall asking you to bring up a discussion first the first sime I deleted it. You ignore that, and provide no reason why it should exist, other than "it should exist" and "I am helping the wiki".
There are multiple ways to help the wiki. There are plenty of articles that need expanding.
Do not create the category again. You've been blocked twice already, the third one may well be longer.
"You've created Corrupt Officials four times now - though I clearly recall asking you to bring up a discussion first the first TIME I deleted it.": You never did that. "You ignore that, and provide no reason why it should exist, other than "it should exist" and "I am helping the wiki".": I ignored NOTHING. I am categorizing all those who are in legitimate positions of power and authority but abuse them. Why do any categories exist? To show connections and links between the subjects of articles.
The categories - Small time crooks and White collar criminals - are oldies and rather random, but they've got some ground of existence. I am not mordicus against this category - it just requires discussion before adding it over and over again.
Not necessarily. It's perfectly acceptable. And can appear after a comma or a period.
And changing it to something that is essentially a longer, uncommon version of the same word doesn't help. Perhaps, in some cases, removing the comma doesn't harm the structure, but you shouldn't change ALL instances without looking at the bigger picture.
It is more uncommon than "and", and has the exact same meaning.
Imagine reading a text where a writer consistently uses one particular word or phrase. Like "however", or "it should be noted", or "as well as". Reading that six times or more in one article would be jarring to the average reader, especially since "and" would have been sufficient.
