Ask Discuz! X Developer: How to hook up the code so that when the user uploads the avatar, perform specific judgment and action?

Issues encountered in the management of the Forum. Recently encountered a large number of such characteristics of the post machine:

• Can bypass registration issues certification, Probation period certification, avatar certification, I estimate that email authentication can also be around
• User names are generally random
• Send ad posts to cheat a lot of links
• Avatar is a very uniform "halo" icon (445 Bytes, SHA1 checksum= 53624f5183539b2f02a799a25136856a84f8c810 )

The resulting effect is as follows:

I want to be able to upload the avatar, recognize the "halo" image, identified immediately lock the user, to block this type of post machine.

Discuz document is not perfect, the online search also has no good plan (note: discuz ban fork redistribution, so is a fake "open source", community support is not active excusable) ... So ask questions and ask two questions:

• If you want to upload your avatar this step to hang code, where to hang?
• what function is used to notify Discuz to lock the user?

I think the head of this thing can not think about the first ...

Can consider the IP, keyword (very effective).
