> it's forbidden to do reverse engineering and change the client First, to play these games (I mean ALL things, touching commercial software development), You must learn, reverse engineering (RE), or hacking, is very special case of laws. It is like strange matter, or dark matter, nobody seen it, but from some measurements considered, it might exist. Same is for RE - to sue somebody for it, one MUST provide good enough proof, that this subject really made him LARGE ENOUGH losses, and it is really done by RE. In real life, this is not always easy to proof losses, it is very subjective thing, so it is even possible, in some WESTERN countries, judges will accept proof, in others will not. Not exactly for RE or hacking, in most countries exists official formulation - smthing like "worthless sue", may be right word, "negligible", meaning, losses so tiny, it is not worth to proceed and usually judges automatically closing such cases. Also, in adequate countries, exists exceptions even for publications of Nazy symbols (usually prohibited) - "for scientific purposes", so if You fit, You could proceed without fear. So You read it wrong. This EULA is for 90% of users, not against hackers (it just will not work against hackers, because, what I said before), and it only mean, if You violate it, for company just will not be possible, to implement their promises which they claimed. For about enforcement, they could forever ban You from use their services (because of fear, that Your work will affect their services for other persons), and also they could do same thing with Your relatives and other connected persons. BTW, unfortunately for You, or fortunate (it depends), losses for 3rd parties and even abstract European values, are important for EU and Western judges, so You should be careful, as (depend on case), judge could decide, You doing contra European values, (in this case they will prohibit Your work), or You doing Pro European values, (in this case they will decide, You could proceed).
