Antvenoms audience is actually on the opposite end of the spectrum than Bajan's, age wise. While there will probably be bad apples, like any audience has, it shouldn't be that bad. Ant himself is mature, from the vlogs I've seen of him. Truth be told, this can't possibly hurt; I find that the community as is right now isn't that great. Maybe a new mix of players and more gametypes will change things a bit.
The mix of a new audience (In my opinion) is just what we need. Think about it, now-a-days everyone is trying to be the best PvPer, there are hardly any players looking for a good time (Well, of course people play to have a good time, but I think you get what I mean.) Right now, who are "our" big YouTubers? Grape (PvP based channel/Player imo), Tomahawk (Although he himself isn't the best at PvP, many of his co-commentators are.), Huahwi (Even though he's "missing", he has had a big influence on this community as a whole.), Toxicwaste (He quit YT, but I think of him in the same regards as Huahwi.) Creeperfarts (Same thing with Toxic and Huahwi, only he's still active.) So if you think about it, all of the influential people in this community are PvP based. Thus making the community seek to be the next big thing, and to be a bit too competitive over MCSG. I think bringing Ant's fans over will REALLY help this community. I am SUPER excited for the new updates to push out and to see some new faces in the community. I said it already but I'm going to say it again, hat's off to MCGamer for their recent work.
