И так начнем. Я выкладываю функции которые мне известны И У КОТОРЫХ 100% РАБОТОСПОСОБНОСТЬ!

АВТОРИЗАЦИЯ ВКОНТАКТЕ:

function vk_login(Login, Pass : string; IdHTTP : TIdHTTP): Boolean;
var
  sl : TStringList;
  text : string;
begin
  sl := TStringList.Create;
  sl.Add('email=' + Login + '&pass=' + Pass + '&expire=&vk=');
  text := IdHTTP.Post('http://login.vk.com/?act=login',sl);
  if Pos('Aoia',text)<>0 then begin
    MessageBox(Application.Handle,'Iaaa?iua aaiiua: Eiaei , Ia?ieu','Ioeaea',0);
    Result := False;
  end else begin
    text := Copy(text,Pos('name=' + #39 + 's' + #39,text)+16,PosEx(#39,text,Pos('name=' + #39 + 's' + #39,text)+17)-Pos('name=' + #39 + 's' + #39,text)-16);
    IdHTTP.Request.CustomHeaders.Add('Cookie:remixchk=5; remixsid=' + text);
    Result := True;
  end;
  sl.Free;
end;

ВЫЗОВ ФУНКЦИИ:
