In a german article there has been an interessting comment from “Paul Janowitz” in regards to the current state of privacy for monero. It also covers a part with potential privacy issues when dealing with RingSignatures. Following you find an auto-translated part of his comment: "If your life depends on privacy, you should definitely know what you are doing, because there are certain edge cases where you invade your privacy yourself, among them E-A-E (Exchange - Alice - Exchange): Assuming that the Exchanges are even different but regulated, you can assume that they share existing data with third parties. Exchange 1, of course, knows what output Alice got, and if it appears in a ring that moves to Exchange 2, it is a hit with a probability of 1:11, or a hit that can be clearly ruled out if the output of E1 was smaller than the input at E2. Summary of outputs: If a user makes daily payouts from a marketplace and this marketplace is infiltrated, the respective outputs (UTXO) are known and if a transaction is propagated, which summarizes these outputs in rings (e.g. 10 rings with 11 possible outputs each), but in each ring exactly one known output is present, one can say with almost 100% certainty, who created it. Very old outputs: The Monero Wallet warns if you want to combine several very old outputs, because statistically, younger UTXOs are used in Bitcoin much more often than old ones and the selection of mixin outputs in Monero is based on this. If I combine two old outputs close to each other into one transaction, it is very likely that these two are the correct ones, even if the ring size is currently 11. IP Address of Propagation: IP addresses are a very strong metadata and are now protected by Dandelion++ by default by first forwarding the transaction to one node only and only after some hops wide. Additional protection is provided by Tor and I2P support, which is not active by default. Against most of the potential attacks mentioned above, the generally known “churning”, where you send a transaction to yourself, already helps. An automatic churning of old outputs similar to Samourai’s liquidity providers is currently being discussed, because with each churn you remove your output further from potentially logging exchanges and other players." PS. It’s also being mentioned, that Triptych will further increase the anon-set while remaining the size of the RingSignatures constant.
