InfluxDB
Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
You can start with that: https://github.com/a100kpm/twitch_smurf_detector
Then you can create features yourself using various api (like opendota) or look for parsing github (i never used parsing tool myself, but i saved the link to this one : https://github.com/skadistats/clarity , no idea how good it is). Since smurf / cheaters are supposed to be a small fraction of all player, you'll end up with unbalanced dataset, so you'll prolly have to do semi supervised machine learning or at the very least supervised with weight.
