I don't mind seeing altcoin ads on the forum, but I do find it peculiar that the forum allows that type of advertising considering how strict they are regarding altcoin giveaways. If someone created a Litecoin giveaway, he would be temp banned together with all users who participated on the grounds of incentivized posting. But the same person can rent out ad space and advertise a project in that way.
I don't really see a connection between those two, they don't look that similar at all. If anything, I would compare allowing altcoin ads with altcoin signature campaigns, which are allowed of course. Regarding this, I am more surprised that someone decided to pay for altcoin ad than forum accepting the offer, given the treatment altcoins usually get on this forum ( in the vast majority of cases deservingly). So yeah, I can imagine how "popular" this useless meme shitcoin Eloncoin gonna get around here.
