People tend to misunderstand two different things:
helping in game mechanics and roleplaying. While the first is about helping in all what is ooc in game, the second is doing all what is ic. Telling how to mine is OOC when you are explaining how it was made possible in the game and how you can do it, IC is when you are telling someone to take the rockpick, hit the wall and the mine and check the rubble for any valuable resources. When you tell someone where is Bronze Doors and how to reach it, it is completly IC, although you could start using words like zones or portals what is completly OOC and unnecessary, even invalid, because you can explain the problem in IC way. Completly different thing is if you (your char) want to help, if you don't want to help, it completly ok and anybody claiming you are acting OOC is wrong. Additionaly while you are IC, that person is acting OOC and its that person fault, not yours.
So we have these two difefrent things:
ooc help and ic help. To first you are highly encouraged, but still have a choice. As for the second, you are here completly free as what to do; nobody can ever OOCly order you to do so.
People just don't really know what is roleplaying and its where the problem is.
Furher, someone who yell at you that you are spoiling RP while you are seeking help ICly, is acting completly OOCly and its that person who spoil the RP.
On the Shakespear topic:
Whoever tell me to speak in his style, I will laugh at his face. I'm not english, I don't really know his style, except from the translations to my language. From this i can tell one thing, its theatrical. It don't have much to do with the way how most of the medieval poeple was talking. Maybe 1% of all the poeple the aristocracy, although i'm not sure if this term is fully valid for this age. Furher, i don't see why I should try to speak in Shakespear style while i know Adam Mickiewicz style much better, unfortunately I don't know english good enough to translate this style into english words.
All where it leads is to not use modern words while roleplaying and as far as your skills allow, try to talk in the way how people was 1000~500 years ago, on the whole earth, not only very east Europe.
