Why are my topics being deleted on the forums?

I made two completely good and thoughtful topics on the Concepts forums, both were about Yasuo. The first one was an idea to fix Yasuo by turning his Resolve into a usable resource and slightly tweaking his abilities to make him more reliant on hitting multiple targets with his tornado/Ult. The second one was an idea to make Tank Yasuo be able to get damage back by putting 10% into runes and going IE and ER when necessary while still building Tank. Neither of these had any toxicity; hell, the only one that was commented on was the second one, which was by some guy who jokingly said to take it down before any Yasuo mains saw it. BOTH WERE DELETED. I had already changed my password recently and never told it to anyone, and I didn't delete those topics myself. Either there's a hacker on the forums deleting random topics, or one of the admins on this site is deleting my recent topics. Whoever it is, you should feel ashamed. It's one thing if people are being salty or toxic, but topics that have no malevolence shouldn't be deleted just because you say so. If you continue this, I'll find ways to get your adminship taken away; if you're not taking it away, take steps to ensure it doesn't keep happening.
