Ad posts

Metod 1 (Easy but broken)

Ad posts are baked in the normal post requests so to remove post ads one needs to break the parsing. To break the ad posts simply rename all occurances of "AdPost" to something else (keep the quoutation marks though), this will remove all ad posts in the main feed, but does not remove posts in the custom feeds :(

Method 2 (Blocks all post ads afaik)

All posts are stored in listables, if you can filter the posts when they get put in those listables you can remove all ad posts. I wrote some custom smali to filter all posts marked as promoted, in Listing.smali (search for .class public final Lcom/reddit/domain/model/listing/Listing;)

Edit the contructor like this:

.method public constructor <init>(Ljava/util/List;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Z)V
    .locals 4
    .annotation system Ldalvik/annotation/Signature;
        value = {
            "(",
            "Ljava/util/List<",
            "+TT;>;",
            "Ljava/lang/String;",
            "Ljava/lang/String;",
            "Ljava/lang/String;",
            "Ljava/lang/String;",
            "Z)V"
        }
    .end annotation

Comment ads

Method 1

This one is not properly tested yet

Search for Error loading comment ads in the whole project, the file should have .source "RedditCommentsPageAdRepository.kt" in the top.

In the same function as Error loading comment ads or Error loading comments page ad is located in return null, like what's shown below.

# virtual methods

Method 2

Rename all occurances of api/comments_page_ads to something else, this will make the network requests to fetch the ads fail :)
