 uep | * so i guess you have too many @word | 04:09:19 |
|  tortillas joined the room. | 06:17:21 |
 @emma:rory.gay | No just too many @ symbols in general | 08:00:25 |
 Yorusaka Miyabi | @ @ @ @ @ @ @ | 11:32:47 |
| Yorusaka Miyabi | Trying seven bare @ symbols | 11:32:54 |

| @emma:rory.gay | Redacted or Malformed Event | 12:28:50 |
| @emma:rory.gay | 15 sure triggers it | 12:29:03 |
 WeetHet | Why are images being deleted? Is there an alternative if I need to send one?
| 15:32:43 |
| @emma:rory.gay | upload it to a file host | 15:33:28 |
| Yorusaka Miyabi | In reply to @emma:rory.gay
15 sure triggers it But if I remember correctly, when I saw such spams, they seems to be always lacking @ symbols in its text parts, or just trying to spam name mentions only in text parts without HTML part in the Matrix message content | 15:33:54 |
| @emma:rory.gay | yep | 15:34:04 |
 @joepie91:pixie.town | wait. the mention detection triggers on @ symbols instead of actual mentions? | 15:34:56 |
| @emma:rory.gay | yes, because its nigh impossible to detect actual mentions | 15:35:15 |
| @emma:rory.gay | because the spammer litterally hinges on the DEPRECATED mention behavior based on body, and not intentional mentions (which would make detection easy) | 15:35:45 |
| @joepie91:pixie.town | you could at the very least detect <word boundary>@<non-boundary character> | 15:35:55 |
| @joepie91:pixie.town | and that could definitely be improved further to prevent misdetections | 15:36:18 |
| @emma:rory.gay | most of the pings dont contain an @ at all, is what yoru was saying | 15:36:18 |
| @joepie91:pixie.town | sure but we're talking about the code that does check for @s | 15:36:30 |
| Yorusaka Miyabi | In reply to @joepie91:pixie.town
you could at the very least detect @ I think they even lack the @ symbol | 15:36:31 |
| @emma:rory.gay | the only case where an @ is in the message, is when a user doesnt have a displayname and it falls back to mxid | 15:36:50 |
| @joepie91:pixie.town | the problem I have with this is not the false negatives, it's the false positives | 15:36:54 |
| Yorusaka Miyabi | for instance they would try like literally saying Emma [it/its] and so on to mass mention | 15:37:04 |
| @emma:rory.gay | that pinged, yes | 15:37:11 |
| @joepie91:pixie.town | yes yes I get that but that is specifically not the case I am talking about | 15:37:14 |

| @emma:rory.gay | blegh | 15:37:29 |

youre welcome | 15:38:12 |
| @emma:rory.gay | tl;dr it splits the string by litteral @ characters, and checks if the result count is above the limit | 15:38:47 |
