This is also relatively simple.
Also when attacking someone, it is vital that a good standard of grammar and/or spelling is used. Refrain from using foul language which will only serve to make you look imbecilic.
It is therefore not wise at all to suggest that a fellow Party member is an undercover journalist or is passing information on to organisations such as Searchlight, unless you have irrefutable evidence that proves your accusation to be fact.
Also never have the bare faced cheek to demand proof from someone who actually has it, when you are accusing them of something that you have no proof for at all, that would just be stupid.
Never ever take on an individual who is honest, these people are a Filthee's worst nightmare, whereas you have to keep alert so as to not get caught in a lie, the honest person is never caught out as they have truth on their side.
Another good element of the personal attack is the hate group. However, when setting up one of these groups, especially when you are an Official of the Party, do not, I repeat, DO NOT leave it wide open for anyone to see and again, under no circumstances add your known friends and fake profiles first.
