It...sounds like you don't really grasp why writer and character counts exist.
The Writer account is just to track individual players. Actual players that manifest in the reality we collectively recognize exists outside the computer. The writer can be a human, a dog, a coordinated group of plants. It doesn't matter. But, for the purposes of this site, it acts as a singular entity. The Writer can be attached to a specific character, sure, but really, it's only tracking the individual player behind a group of characters, whatever the player is defined as being.
The Character accounts are the individual entities that exist within this RP universe. They are not subordinate to writer accounts in anyway when In-Character, they just fall under the grouping umbrella marked by a Writing account when Out of Character. If you have Johnny Ridiculouslyoverpowered as your Writer account, and Mary Hasntquitegoneoverthetopyet as a Character account under Johnny's umbrella, should Johnny be found unacceptable by the terms of the site, it by no means declares you can no longer use Johnny's account. It also doesn't mean Mary needs to fill Johnny's old shoes. The Writer account does not need to check in periodically to make sure it's still in use, particularly if the Character accounts clearly are.
If, for whatever reason, you find you can't stick with a single character for more than a weekend, feel free to change the name of your Writer Account to a handle, like a brand, like Messiah Complex or 2Xtreme4u, and let all the characters you make fall under that brand name. It should be fine, so long as you don't attempt to roleplay with your handle, especially 2xtreme4u, as a character name.
