Does the old account have a negative trust rating?
Is the old account a Jr member ranked or above?

[...] Later some of us (from the group) wanted to make our own project and we were not able to post from our new accounts here. We created multiple accounts and it was not working. We wanted to launch the project on the 1st January and we were in hurry because we were running out of time so we utilized this account of Raj upon his permission (donation).

You can check our new accounts created yesterday which were not able to post anything.
