- Explicit profanity: fuck, shit, damn, hell
- Slurs and insults: bitch, cunt, faggot, nigger
- Death wishes: KYS, kill yourself, go die
- Aggressive commands: uninstall, delete, uninstall
- Skill insults: noob, trash, garbage, worthless
Performance
- Speed: <1ms processing time
- Accuracy: 100% detection of explicit toxic words
- Memory: Minimal memory footprint

π Error Handling
The bot includes comprehensive error handling with graceful degradation:
Custom Exceptions
from message_validator import (
ToxicValidationError,
ModelLoadError,
InputValidationError
)
try:
result = validator.validate_message("test")
except InputValidationError as e:
print(f"Input error: {e}")
except ModelLoadError as e:
print(f"Model error: {e}")
except ToxicValidationError as e:
print(f"Validation error: {e}")
Graceful Degradation
Model loading fails | Uses fallback methods |
Word filter fails | Continues with ML pipeline |
RAG fails | Uses fine-tuned model only |
Input validation fails | Returns error result |
GPU unavailable | Falls back to CPU |
Error Result Structure
result = ValidationResult(
is_toxic=False,
confidence=0.0,
result_code=0,
result_text='error',
processing_time_ms=12.34,
pipeline_stage='error',
error_message='Detailed error description'
)
π Monitoring & Logging
Logging Configuration
Logs are automatically written to:
- Console output (with Unicode-safe handling)
- toxic_validation.log file (UTF-8 encoded)
import logging
Performance Monitoring
metrics = validator.get_performance_metrics()
print(f"Average processing time: {metrics.average_processing_time_ms:.2f}ms")
print(f"Word filter efficiency: {metrics.word_filter_hits}/{metrics.total_requests}")
print(f"Success rate: {metrics.successful_requests}/{metrics.total_requests}")
Health Monitoring
health = validator.health_check()
if health['status'] == 'healthy':
print("System is operational")
else:
print(f"System issues: {health['error']}")
π§ Advanced Usage
Batch Processing
messages = ["message1", "message2", "message3"]
results = []
for message in messages:
result = validator.validate_message(message)
results.append(result)
toxic_count = sum(1 for r in results if r.is_toxic)
avg_confidence = sum(r.confidence for r in results) / len(results)
avg_processing_time = sum(r.processing_time_ms for r in results) / len(results)
print(f"Toxic messages: {toxic_count}/{len(results)}")
print(f"Average confidence: {avg_confidence:.3f}")
print(f"Average processing time: {avg_processing_time:.2f}ms")
Custom Word Filter
validator.toxic_words["custom_word"] = ["custom", "cust0m", "c*stom"]
del validator.toxic_words["some_word"]
Pipeline Configuration
validator.config['pipeline_enabled']['rag'] = False
validator.config['pipeline_enabled']['embedding_classifier'] = False
validator.config['confidence_thresholds']['embedding_high'] = 0.85
Custom Configuration File

π οΈ Troubleshooting
Common Issues
1. Model Loading Errors
Problem: ModelLoadError: Failed to load models
Solutions:
ls -la model/
python -c "from transformers import AutoTokenizer; AutoTokenizer.from_pretrained('model')"
pip install --upgrade transformers torch
2. Memory Issues
Problem: Out of memory errors
Solutions:
validator = Message_Validation()
import torch
torch.cuda.empty_cache()
validator.config['model_settings']['batch_size'] = 1
3. Performance Issues
Problem: Slow processing times
Solutions:
validator = Message_Validation()
validator.config['confidence_thresholds']['embedding_high'] = 0.8
validator.config['pipeline_enabled']['rag'] = False
4. Unicode Encoding Issues
Problem: Unicode errors in Windows console
Solutions:
import sys
import codecs
sys.stdout = codecs.getwriter('utf-8')(sys.stdout.detach())
Performance Optimization
1. GPU Acceleration
import torch
print(f"CUDA available: {torch.cuda.is_available()}")
print(f"GPU count: {torch.cuda.device_count()}")
print(f"Current device: {torch.cuda.current_device()}")
2. Batch Processing
messages = ["msg1", "msg2", "msg3", "msg4", "msg5"]
results = [validator.validate_message(msg) for msg in messages]
3. Caching
from functools import lru_cache
@lru_cache(maxsize=1000)
def cached_validation(message):
return validator.validate_message(message)
