editors are professionals but they watch and responsible for the 'category' with which most of them belongs too in having their own listings, that makes them to stand in the que of competition and its a fact that we also can't ignore.
It is not a fact, just a particularly nasty Internet myth, that is quite easily dispelled.
Let's play a game to see if we can shoot holes in that sad tale.
Let's start by trying to agree on the number of categories. For argument sake, let's say 500,000. The number is closer to 700,000, but we won't argue the difference.
Then let's agree on the number of editors. Let's say 10,000, even though the number hovers at around 7,000, but 10,000 makes for easier math.
Now, let's guess at the number of websites owned by each editor. Some have many, many have few or none, but for argument sake, let's say 5 per editor.
So if each editor has 5 websites, and each website is in a category that the editor edits (wildly unlikely, but we're not letting the facts get in the way here), and there are 10,000 editors, then somehow that accounts for only 50,000 possible categories. Way short of the 500,000 active categories.
So iN this horrid myth, if editors are somehow keeping competitors out of categories where they have their own websites, this could only be happening in 10% of the categories.
Now let's use some numbers that are closer to home: assume 7,000 editors and 650,000 categories. Let's also assume a more realistic 3 websites per editors: that's 21,000 categories out of 650,000, then that is fewer than 3.5% of the categories that are mythically blocked. For this to work, each editor would have to have about 35 websites.
Then there is the joker in the deck: there are about 200 or so editors who are allowed to edit in any category within the directory. That makes it pretty hard for an editor to block or control a category. This right to edit in any category includes the right to edit (without asking permission) in categories where there is a named editor.
Then there is the public complaint system. If you were to file a complaint saying that ODP editor spectregunner is blocking competitors from the category of category/subcategory/subcategory/subcategory it would only take a few minutes for the group we call meta editors to look at my public (within the editing community) editing logs and see what my history is with regards to that category -- since the first day I was an editor. Any editor can see any other editor's logs. It is like visiting someone's home, using the bathroom, and looking through the medicine cabinet.
You see, it really isn't possible, let alone practical, for this to be a widespread practice.
Does it ever happen? Sure, anything can happen. I might even grow hair again. But when it does happen, the members of the editing community eventually find out, and then there is another ex-editor making the rounds of the webmaster forums crying "woe is me" and complaining that they were kicked out for no reason at all. And certain parts of the webmaster community will embrace them and make heros of them.
