I thing I know why eye enn g is getting bleeped out.
For a while on the budget board people were talking about an internet bank with the same initials.
One thread about it, turned into a long,drawn out thread with people begging for $25 referrals. Then other people started to post their own threads about it... and the cycle continued. Soon there were more referral threads than actual info.
No, not a dirty word!
