Dangerous sites?

Court

Hi everyone. I started comping on this site way at least ten years ago. Over the years I have comped quite sporadically with my last break being about 4 years. I've only started again in August and I can feel the difference for sure. So many IG and Twitter comps now and a few sites that feel really dodgy to me. I apologise as I cannot remember which ones make me nervous off the top of my head other than twizl, but I was wondering if there are sites out there that you automatically skip or have had a bad experience with? Cheers!
