I dont think they are calling you Peacons a spammer, its the site to which you posted the link that is being identified/accused as a site that has spammed people before.I'm not spamming ,just sharing a supplier I've found to be reliable.
For supplies use xometry.com/supplies
Yes you are missing something but their site is not exactly the most user friendly layout ive seen before!I don't see anything there that they sell metal. Am I missing something?
