SponsorSystem

SponsorSystem is a trust-based sponsorship and player accountability plugin designed for Minecraft SMP and community servers.

As servers grow, it becomes harder to control who joins the community. A player may invite a friend, that friend may invite another person, and eventually unknown players can gain access to the server without any connection to the community. SponsorSystem helps solve this problem by creating a sponsorship system where every new player is introduced by an existing member.

How It Works

Players who join without a sponsor are placed into a verification state. They cannot fully access the server until another trusted player sponsors them.

Existing players can invite new members using the sponsorship system. Once the invited player accepts, they become connected through a sponsor relationship.

Example:

Alex sponsors Steve

Steve sponsors Bob

Bob sponsors John

This creates a community trust network where players are connected through the people who invited them.

Features

Sponsorship System

• Players can invite and sponsor new members.
• Each player can have one active sponsor.
• Sponsors can sponsor multiple players.
• View sponsorship information and history.
• Track who invited who.

New Player Protection

Players without a sponsor are placed into a restricted verification mode.

During verification:

• Normal gameplay access is disabled.
• Movement and interactions can be restricted.
• Configurable effects can be applied.
• Players must receive sponsorship before joining the community.

Sponsor Accountability

Sponsors are responsible for the players they invite.

If a sponsored player breaks server rules, administrators can report the player and apply consequences to both the offender and their sponsor.

Example:

Steve destroyed another player's base.

Steve: 48 hour temporary ban

Alex (Sponsor): 4 hour temporary ban

All punishments can be customized through the configuration.

• Griefing
• Stealing

Each punishment can define separate actions for:

• The player who broke the rule.
• The sponsor who invited them.
