No, Freebie Central's team avoid games with suspicious giveaway links, including cracked games.
Our guild has separated platform channels, meaning if you want to follow just Steam games, you can!
As soon as we find them, we post freebies we're sure aren't going to expire as soon as we post them. In some occasions, we have no idea when they expire.
On our Discord server, you can post links in the #freebie-talk channel. If we think it's worth it, we post it, crediting you for the help.
Keep in mind that posting cracked games/suspicious links will get you kicked.
