Truncate scripts from https://plg.bet/provably-fair/coinflip

[SjonHortensius]

3v4l is used by an apparently pretty popular betting site to verify bet outcomes. These scripts pollute the database without much use. I'm considering removing these scripts (it seems there are ~ 250k submits right now) and notifying the site owner to either use another service, target single versions for their submits or schedule a cron to remove these submissions from the db
