3.1.5 Considerations

1. Pagination & Content Loading

SUM+1 implements cursor-based pagination to handle large volumes of user-generated content efficiently. Posts are loaded incrementally using infinite scrolling, reducing API load and improving the user experience. Each request retrieves the next set of posts based on createdAt, ensuring smooth navigation.

sqlCopyEditSELECT * FROM posts 
WHERE createdAt < :last_fetched_timestamp
ORDER BY createdAt DESC
LIMIT 20;

A "Load More" option is available for users who prefer manual content retrieval.

2. Content Filtering

Posts can be filtered by coin interest, user follow lists, and trending hashtags to ensure relevant and personalized content.

• Coin Interest: Users can subscribe to specific tokens or memecoins, displaying only relevant discussions.

• User Follow Lists: Posts from followed traders and syndicates are prioritized.

• Trending Hashtags: Posts tagged with high-engagement topics are dynamically ranked.

sqlCopyEditSELECT * FROM posts 
WHERE coinInterest = :selected_coin 
ORDER BY createdAt DESC 
LIMIT 20;

Indexes are used on coinInterest and userId to optimize query performance.

3. Moderation & Spam Control

Content moderation tools allow administrators and post authors to manage platform integrity.

• Post and Comment Deletion: Post authors can remove their own content, while admins can take action on flagged posts.

• User Banning: Admins can suspend accounts that violate platform guidelines.

• Reporting System: Users can report inappropriate content for review.

Automated spam detection is in place to prevent abuse. Machine learning models analyze content for spam indicators, and rate limiting is enforced to prevent rapid posting.

sqlCopyEditDELETE FROM posts 
WHERE id = :post_id 
AND (userId = :requesting_user OR :requesting_user IN (SELECT id FROM admins));

Redis-based caching and API rate limiting mitigate excessive requests and bot activity. Keyword blacklists are maintained to filter scam content.
