It is certainly a surprise to see a professional company making this sort of error. It is good that Astak know to avoid this slip in future.
I can understand rando's disquiet; my workplace email address is on the web and attracts a lot of spam. A lot of people really don't want their addresses publicised for precisely this reason. One can't be sure that none of the other 213 people is a spammer.
Incidentally, I'm looking at the "similar threads" in the box beneath this post. Aztak seems to be a common spelling variant. I bet that Sony don't have this problem. (That was intended as a frivolous remark.)
More seriously, I suggest that we don't take too much notice of spelling errors: some forum members are posting in their second or third language; others are dyslexic or poor typists. And we don't want to be pedantic, or unwelcoming to newer members.
