Others get away with it because they've been around a long time and many know them and they've established a bond. When newbies come to the forum and try name a fig, some try to tell them how to name figs. To me, it's ok to name a fig. However, it does help to prefix a found fig with the word, "unknown" adjacent with the street name where you found it. But it's perfectly alright to name unknown figs any thing you want. No one here is judge or jury over naming figs.
If you old guys remember, a bunch of folks left this forum because some were mad at others naming figs. They wanted Jon (our administrator) to jump in and support their clique. Well, those that know Jon, knows he's not cliquish at all. When he didn't support the clique, they got mad at him, left the forum, deleted all their post, created their own fb page or forum.
To me, life's too short to let others try to be controlling. So IMHO, name your unknowns if you want.
