What I was wondering is that Why there is this word? why FOR CONSIDERATIOn when you are seeking for answers for some times now? isn't a fair treatment from their team to answer and address everyone that seek respond? does it mean they answered you because of different reason and directly because of your concern?

Maybe it's the effect of bitcointalk forum 
Well that is the most effective way to alarmed the team of each site , when creating a topic against them directly because they knew how much publicity they need from bitcointalk so congrats at least they are responding now.
