On the 20th of december 2020 (Almost a year ago as of now) was the former Spigot member Kangarko removed from the SpigotMC Forums. The reasons were not publicly stated at first, but after he tried to blame SpigotMC on being at fault here did MD_5 make an announcement, clarifying the actual reasons and the current situation. The reason he stated in that post was repeated violations of the forum rules, primarely abuse of the resource's update feature for promotional actions (i.e. advertisements).
With that said do the Forum and Software have a lot of negative things, that annoys developers, server owners and forum users alike for quite some time now.
To bring some light to this do I now list both positive and negative things about SpigotMC.
