It is indeed a very good question, so much so that I once asked a rather attention seeking question along those lines, ie 'Do you find me sickly and nauseating or am I just helpful?'
I am of course being rather pompous and presuming I may be in this group to which you refer.
From my stand point I try to help, calm, mediate not to be seen as angelic, but rather that it is my nature. Yes there is a possibility of 'feeding' the attention seekers, but like to think have sussed them out, the only problem is the possibility of the 'Cry Wolf' scenario.
