Im sorry but "paying" to get a ban lifted is absolutely ridiculous.

You mention people selling accounts cheap and what not....
It has been mentioned to add a character market before. Zezenia could easily take 10-20% of the actual cost. And provide a safely transferred bought character to your own account. This is a business tactic. What you mentioned is a desperate out for people who got banned for breaking the rules.

You want to compare real life to the game so here it is...
Technically speaking, getting banned until deletion would be equivalent to landing a 1st degree murder charge. Where you will never get out of jail. That being said, if you were charged for murder (Banned until deletion)..... why would you get bail? You dont. You were already charged and jailed. You cannot now post bail after being charged for 1st degree murder now can you? Its a life sentence, as goes for the banned for deletion. Also a life sentence. :) So get use to it cause you will never see those banned until deletion characters, bought back into the game by paying a fee. It really makes no sense what so ever.

Things that can increase profit to Zezenia;
-More frequent Updates (Maps, Creatures, Quests, Items, Professions, Revamped Dungeon System)
-More communication to the players
-Character Market
-More to Pets
-Tons of other small things that can just put a nice cherry on top of things
-Im sure theres more people have in mind

Doing these small things will increase player base, thus providing in more income to the game. Its about pleasing and appealing the audience... We need more things to do, more systems, revamped areas, new items, meaningful quests with a story to it. Things that attract people to play a RPG game. Theres no real "End".
Each ending though can have an expansion leech on after it. Just like every RPG game pretty much does these days. To continue the game for high level players, but also attract new ones with adding more appealing features and things to do in the game with each new big update.

When Zera started, everyone bought pets. Im not saying it was an insane amount, but its safe to say Zezenia made about in the range if not more then 2kUSD in the launch off Zera from pets/pcards.. Imagine doing the things I listed above. People would have more of an incentive to buy pcards and buy into the game. Or support it if you want to call it. Me I support games that show me they are actually putting time into the game im spending money on. Devs need to show us.... their playerbase, what we would expect from a "growing rpg" game. Is more communication and more updates. More test servers. More trials and errors. Take risks. Learn, grow, overcome....Doing this is a step in the right direction on a successful MMORPG.

Im sure there is people here who "Will keep spending if you keep providing, but you stop providing, I stop spending" kind of moto.

Or just dont bot/cheat to begin with?

You think in your right mind, they will add a fee for players to buy to unban their cheated/botted accounts, to get the hundreds of dollars of items and cash off it. So they could resell it....and their botted char?
This is clearly a horrible idea, and not only does it promote cheating. It gives players the option to cheat and get caught but pay out to get un banned. That's truly stupid
