If you have a trust and keep getting glined for clones, this is probably because you are breaking the clone rule. A clone is when you have more than one connection from a single address (ident@host).
If you exceed your trustgroups
total number of clones (the number of clones allowed with the same hostmask) or;clones per ident (the number of clones allowed with the same ident)you WILL BE G-Lined. Repeated abuse of either the clonelimit or identlimit will result in the trust being revoked and all users on it G-lined.
