All posts must be related to PlayStation trophies. This is very straightforward: pretty much anything is allowed here so long as it's related to trophies. Posts related to Xbox/Nintendo/Steam etc achievements are not allowed.
Posts: If any image within a post contains a spoiler, the Spoiler tag must be applied. Even with spoiler tag applied, text spoilers are not allowed in titles.
Comments: Comments that contain spoilers need to use the spoiler function when not related to the subject of the post, or when commenting on posts specified as spoiler free.
Simply put: if you post a screenshot of a trophy it should be your trophy. There are minor exceptions like things that are obviously memes/jokes, but simply presenting someone else's achievement as your own isn't allowed.
Offering services that involve others sharing account information with you in order to earn them trophies is strictly forbidden and will result in a ban. These services are too susceptible too theft and scams.
Non-game specific posts should being with either [Other], [Discussion], or [Meta] in brackets in the title. Posts covering multiple games can have one, some, or all of the games, or just [Multiple Games] in brackets at the beginning of the title.
