As part of stricter anti-spam measures, new posts that have large amounts of content similar to many other posts are automatically hidden. You'll know this because your entire post will be highlighted in red and only visible to you.
Unfortunately, this means dumping crash reports or logs directly in your support thread will trigger it. To avoid this, please read the FAQ before posting and provide a link to your log or crash report on an external paste site (such as pastebin) instead.
If your thread is automatically hidden, you'll need to create a new one or wait for a moderator to manually approve it and remove the log from your post. When creating a new thread, make sure you only provide a link to an external paste site and do not dump logs directly in your post again as doing so could risk your account getting banned.
