There are different views on the matter, but in general, you are better off promoting what goes against the teachings of Islam, and you should seek forgiveness from Allah for what happened in the past. However, if it is normal, then it should be okay, and Allah knows best. (Arabic source)
For this, you need to be really sincere when you decide what you are going to promote and what not, and it might be delicate, and you should be responsible of what you are promoting. I remember once I was in a similar position, and decided not to promote an anime as its main theme was about gods and so on, and that it was directed to children. So basically it is boring for adults, and will be mostly watched by early teenagers, so I talked about it to my peers, but not to youngsters.
If you really want to do it, then make sure it is proper, and there is no need to say that eechi is improper. So you either take the responsibility, or let it off.
