David Schwartz, recognized as one of the original architects of the XRP Ledger and known on X by the handle JoelKatz, has introduced a new personal policy regarding interactions on his X account: he is now blocking users who insert cryptocurrency-related comments, accusations, or off-topic content into discussions outside the realm of crypto.
Crypto Comments Spark Change
Schwartz highlighted that he has recently experienced a notable increase in replies containing cryptocurrency references or insults that are posted on threads unrelated to crypto topics. The recipients of his non-crypto conversations often find that their followers are then exposed to these off-topic or inappropriate responses.
He described the practice as placing those users in a difficult situation: they must choose between tolerating unwanted posts or blocking him to avoid future issues. To prevent innocent users from being caught in this scenario, Schwartz has opted to proactively block the accounts that post irrelevant crypto content or accusations in unrelated discussions.
A significant proportion of these disruptive posts include accusations against him, ranging from fraud to scamming. Schwartz stated that he will block this behavior in all cases, regardless of whether a comment is critical of XRP or even intended as praise.
Distinction Between Criticism and Spam
While Schwartz emphasized that he does not oppose criticism or even public allegations against him, he drew a firm line: such remarks must carry substantive content rather than mere insults. He stressed that context is important, expressing that criticism should be posted either in the user’s own threads or as direct replies to relevant topics on his feed.
He cautioned against following him across the platform solely to label him a “scammer,” or, conversely, to inject positive XRP comments into unrelated conversations. According to Schwartz, such off-topic replies frequently upset the users whose posts are co-opted for these exchanges.
Schwartz indicated that he will grant unblocking to anyone already affected by this rule, provided they promise not to repeat the disruptive behavior and find a way to notify him. The offer stands regardless of any ongoing personal disagreement, as long as comments are kept relevant to the topic at hand.
Some community members countered that their frustration with Ripple’s performance or unmet expectations justified their criticism in his replies, while others argued that Schwartz’s approach limits accountability.
Focus on Conversation Quality
Schwartz clarified that his primary concern relates to maintaining the quality and relevance of conversations, especially when his replies appear in other users’ timelines who did not initiate or welcome crypto commentary. He underscored that his stance does not extend to broader debates about XRP or Ripple, but rather to the specific issue of irrelevant replies disrupting non-crypto discussions.
This approach marks a clear boundary regarding the topics and spaces where he is willing to engage. He remains open to criticism and discussion, as long as these exchanges occur in suitable contexts. However, off-topic posts—whether antagonistic or supportive—in unrelated threads now result in immediate blocking.
David Schwartz is the CTO at Ripple, a San Francisco-based fintech company, and a leading figure in the development of the XRP Ledger, an open-source blockchain protocol designed for fast and efficient cross-border payments.

Schwartz’s actions signal a move toward more structured, relevant discussions on his X timeline, aiming to reduce spam and protect the experience of users involved in non-crypto topics.
