I guess so.... I'll take mine down just in case, but I'll keep a link on my profile (seems good right?)
Setting it as your home page is more out-of-sight-out-of-mind, so while I wouldn't advocate doing one over the other, I don't think it's a serious offence and at least you took the first step in removing it. If you ever want to trade full-time on Smogon though, a trade thread is recommended and I know I personally find them usually easier to browse around than a spreadsheet (where you may not be able to C + P).
Yea but its really hard to write down all thr time what i have
If you don't want to create a trade thread, no one's telling you or forcing you to. The last two posts here you've just been saying about how hard it is to keep track of everything you have and haven't really been posting anything substantial.
As a recommendation, get your stock in order before you think about creating a thread, otherwise you'll just have empty posts for a long time. I personally organize my boxes by Kanto-Kalos breedables in order of the National Dex. If you have Pokebank, this is a lot easier too as you can just search by "breed, Dex Number, etc".
If you want to stick to casual trading, then this is the thread for you.
