You probably won't get blocked for posting on your wall. However, if it turns out that you're annoying too many others and they request that you stop, once that happens you might want to do so. Staff are equipped with other tools than just a banhammer.
Please stop creating pages regarding upcoming information and fan-made ideas. Share stuff like that on the Geometry Dash Fan-Ideas wiki. If you continue, moderators will have to ban you for a bit, since doing what you did is considered vandalism. Thank you.
This wiki is for official, released content only. NO fan-made ideas. The pages you created weren't about official Geometry Dash content, they were fan-made ideas. So, I would stop if I were you, because if you continue, you're gonna get in some SERIOUS trouble by the moderators...
Now being officially warned for editing the user page of a non-user. Continued unconducive or non-sensical edits, including on your own user page, and especially if observed doing so outside of the main article namespace (including creating such pages), will result in penalties.
