Wow, this really worked for me when other plugins didn't. Is it possible to have AJB be "disabled" by default? After restarting it is defaulting to enabled and I have to manually /ajb toggle each morning to turn it off. Many of my players use proxies and I only want to engage this plugin when there is a problem. Thanks!

Does this plugin work for "normal" players, too?

We have some troll users and want to prevent fast rejoins if possible.

So users have to wait a minute after logout til they can rejoin the server for example.

@TheKillHD Maybe your MySQL server is closing the connection before the end of the transaction.

Do you see any errors in Console with Debug enabled?

@Qalle Will see for version 6.0. Currently it looks like many IPs are Blacklisted too on StopForumSpam, which makes this check not efficient.

Could you provide support for DNSBLs such as sbl.spamhaus.org?

Similarly to what this https://mods.curse.com/bukkit-plugins/minecraft/dnsbl plugin is doing, except configurable, please.

As I said many times, this plugin won't help you with bots that don't use Proxies.

You can either block them by configuring your firewall (if you can), or by using the AuthMe AntiBot feature or other rate-limiting/whitelisting Anti Bot that you can find online.

Note: Whitelisting AntiBots will rise a Whitelist that will last until the attack ends, this will also block normal players from playing.
