Prohibiting the output of certain IDs Laravel

When I create a post, the user selects a server(guild), and I need to prohibit the selection of a server that was previously created

I tried via @if($server->title != $guild->id) But it doesn’t work

I also do @if(Auth::user()->id === $user->id) to check the output to a specific user of his server,Maybe it gets in the way

@foreach($users as $user)
                    @foreach($user->guilds as $guild)
                        @if(Auth::user()->id === $user->id)
                            @foreach($servers as $server)
                                @if($server->title != $guild->id)
                                        <option value="{{$guild->id}}">{{$guild->name}}</option>
                                @endif
                            @endforeach
                        @endif
                    @endforeach
                @endforeach
