Mr_Bubblezy has recently been posting some problematic feedback in the Ideas forum, oftentimes commenting erroneously on extraneous material and just stating something is "good".

Hey dude! Not sure if you have read through this [link to How to Write an SCP] before but there is a lot of information for you to go through, this is all to do with how to write a concept up and what you can and cannot put in it, also some special tricks like how to put bold font and links in your work. Also pretty cool concept although as BudsNCircuits pointed out you should only put small paragraphs on here rather then a full 'draft'. You can add a link to your draft in the thread you post; Hope this helps. :)

It's a really cool idea for an SCP. Your writing skills are good for a beginner but try to write in longer sentences rather then many short ones, limit the use of full stops and use more of commas, colons and semi-colons. Also when writing up a draft be sure to not use a number, it is advised to use SCP-XXXX when posting on the ideas and brainstorming forum.
Otherwise good start!

I would say it's a cool idea for a ride although it is simular to SCP-002 but you could always deviate from that SCP. You would have to think about how the public hasn't figured out its strange properties and where it came from as it is in an already-existing park (did it just pop out of nowhere or was it built and then someone died on it, after the death it started being an anomaly). All in all though its a cool concept.
Sent them the usual "please be more conscientious" PM. Keep an eye on.
