Ok for those who are still interested in this Topic. 3 years later after I worked with TOOMICS with my series, I'll share my experiences with them, some warning signs/red flags, and I guess some few positive points.
Green Flags
1. Professional
2. Have a history of being a legal business
3. Does things legally
Red Flags
1. Never does any kind of promotion for my series like they were supposed to
2. Changed Project Managers 4 times within 3 years
3. Lack of communications, they'd only inform me they had published my series 3 months after the fact and that is after someone else alerted me about it thinking it was illegal
4. Safe for my first Manager who was actually the one who convinced me to sign, nobody else seems to CARE about my series or even read anything about it
5. Doesn't offer any kind of creator support
6. If your series doesn't do well financially they ask for "mutual termination" of the contracts (but that's probably your fault, not due to point #1)
I have worked with Tapas for almost as long as with Toomics, but the difference is like Heaven and Earth. Toomics isn't worth your time, in my honest opinion.
