I could seriously go either way, because I see the fun and harm in both. While it is more mysterious to say ABC, the cookies etc, to a point someone may be able to figure out what house that is after the first day too. Especially if you know what school that person is going through recruitment at. For example, if a PNM said, "The Oreos did a really cute skit. The girls wore these black dress and the theme was something like this..." (We know this happens in rush threads), plus the PNM listed where they went to school at in the beginning of the thread or in other post. It's not to hard to guess the house, if you go to that school or know someone at it.
I guess the main thing is this....

PMN can decide whether they want to use actual names or not. So whether an actual name is used or not...
PMN's.... Take caution with what you are writing
Actives/Alums.... Take caution in what you are reading


PMN's you never know who is reading what you wrote, and then may act childishly, immature, obsessively about it. Actives/Alums shouldn't throw a hissy if a PNM may say something about a chapter that may not be nice. It;s their opinion, just as it was your's when you went through. Furthermore, if its your org and they like it at start, dont get too happy because opinions can sway quickly
