Here You can find information about https://getsession.org/ messenger open community server (SOGS) SQL triggers to deal with SPAM and to reduce abuse.
A) use tool and triggers list https://codeberg.org/gravel/pysogs-sql-triggers (possibly better, more complete/complex solution)
# Setting up PySOGS SQL CLI:
cd /var/lib/session-open-group-server/ # possibly it is good to install into a folder you regularly backup
git clone https://codeberg.org/gravel/pysogs-sql-cli && cd pysogs-sql-cli; sudo usermod -aG _loki $USER && sudo chmod g+w /var/lib/session-open-group-server/sogs.db && ./test.sh && echo "export PATH="$PWD/bin:\$PATH"" >> ~/.bashrc && source ~/.bashrc
# Installing SQL triggers:
cd /var/lib/session-open-group-server/pysogs-sql-cli/ # go to a directory of the previously installed pysogs-sql-cli
git clone https://codeberg.org/gravel/pysogs-sql-triggers/ && mv pysogs-sql-triggers/sql/*.sqlite sql/
# customizing triggers
View all trigger files and adjust it to your needs if needed. For example look for XXXX and replace by a number and similar.
nano *.sqlite
# Running the tool:
sogsfilters # then use arrow keys, enter or q
# Debugging
sudo journalctl -f # this should follow system, SOGS messages
Try to do an action in Session, which triggers the triggers to see if it worked/no error emitted.
B) if you do not want to use that convenient tool, you may manually use following scripts/triggers (following triggers are only part of what the pysogs-sql-cli offers)
PM/DM disabling:
A)
Disallow only new regular users from sending private messages while allowing older users (helps reducing spam and illegal content spreading) - based on this (https://web.archive.org/web/20240628055047/https://stuff.oddch.at/51398/restrict-new-users-from-sending-dms) Oddchat article:

chmod +x session-sogs-prevent-disable-pm-dm-for-new-regular-users.sh

Deny long message:
Ban user who posts too long text message (by default it is 10 pages of text - 10x1800 characters) - based on this (https://web.archive.org/web/20240628055133/https://stuff.oddch.at/51402/ban-user-for-posting-large-messages) Oddchat article:

Cleanup banned user content:
Delete messages and reactions (from all rooms, except user defined room) of a user who gets banned (meaning someone bans a user and automatically their content is removed from everywhere) - based on this (https://web.archive.org/web/20240628060736/https://stuff.oddch.at/51401/delete-messages-and-user_reactions-when-a-user-is-banned) Oddchat article:
