Nobody accused you of being a bot. I was the one who called it out as an ad. On a server that specifically says no ads.
Your username is a store. The posts you made all linked back to your store’s blog.
You may not have had bad intentions, and I totally believe you wanted to help. But doing so under the name of a company, with posts that solely link back to that company… Is advertising.
If you want to advertise for fastek, put up a lemmy server of your own, on your domain, with your money. Or find an existing server that doesn’t have ‘no ads’ as a rule.
