Hello guys, Do you think it’s possible to censor crypto address in topics? Not even sure a regex can do that… am I right? Thanks.

[image] Salocin: I was wondering if AI could not solve this problem more widely I don’t think this is so complicated that we would need AI to solve it. What they all have in common is that they’re a pretty long string of characters without any spaces, so ^[a-zA-Z0-9]{25,60}$ would get you pretty far.

What’s a crypto address? What do you mean by “censor” - hide? block? force review/approval?

Ok, this is a example of a crypto address : 0x6dD9EF7464A3c28f1285bCCB95bE83dC4A9De3ca Not easy to detect by a regex imho. What I would like is that if a member tries to publish an address of this type it is obfuscated in the public message. And possibly visible for moderation but this is not necessarily the most important.

[image] Salocin: Not easy to detect by a regex imho Very easy to detect by a regex since it’s always 0x and then 40 characters a-f and numbers. /^0x[a-fA-F0-9]{40}$/g BTC addresses would be ^[13][a-km-zA-HJ-NP-Z1-9]{25,34}$ (13 followed by 25 to 34 characters, excluding l, I, O and 0) Add this to watched words and don’t forget to enable settings - posting - “watched words regular expressions”.

[image] RGJ: /^0x[a-fA-F0-9]{40}$/g Depending on which regexp engine you’re using it can be written as /^0x\h{40}$/ :wink:

Thanks both. If I’m not mistaken, there are as many sequences of addresses as crypto tokens. The example I provided is for the LINK token, but for ETH, BTC, XRP… and hundreds of others how to do it? But in general it is easy to recognise a crypto address visually, this long sequence of characters is rather typical, so I was wondering if AI could not solve this problem more widely. It seems feasible to you in Discourse (a plugin maybe?)

You’re right, I assume that this regex can detect 99% of the addresses. Thank you very much for your help.
