Could you write a plugin protection from reconnecting to the server? That is, if you went out from the server, then go back to it you can only after n seconds.
Try DelayedReconnect. It's a quick plugin I just wrote. It depends on FirstLastSeen to check when a user was online last time. DelayedReconnect makes a new config file at first start. It says SecondsToWait: 60. Change the value (60) to anything you'd like the users to be waiting. If this plugin works correctly and you want permissions (like admins not having to wait) or other functions then just contact me any time.
Don't work! I installed plugin FirstLastSeen and this P.S.: Is there a way to do without the plugin FirstLastSeen?
It would be helpful if you would tell me what exactly doesn't work and if it gives errors to copy those and post them here (or pastebin). If you want to do this without FirstLastSeen then it has to be written from scratch including some kind of last-seen part (background only). I could try to do this but it would take some time. Tell me if you want me to...
Ok, then I'll start building the plugin from scratch for you instead of using another plugin's api. It was way easier then I had expected. I just had to make the right calculations. It currently stores the player information in the config file (apart from the config to keep it clean). If it ever turns out to be creating a huge config file then contact me and I'll create some sort of clean-up part of the script. I don't think this will be needed for small/medium servers. The plugin doesn't depend on anything, it's a stand-alone plugin. You can give users which should be ignored by the plugin the permission node delayedreconnect.ignore You can download DelayedReconnect v0.2 here.

Compatibility for CraftBukkit 1.1-R6 Killed v0.1 and v0.2 download links Download DelayedReconnect v0.3
I will update it as soon as possible. The dl.bukkit.org website is currently down, so I can't download the latest builds. EDIT: There seem to be no API bugs / errors whilst compiling and there are no bugs / errors when I test it on a local server (CraftBukkit 1.2.4-R0.1 #02120). If I you did get errors it should be helpful to send those including which CraftBukkit build you are using. Pr07o7yp3
